Disambig again

This page is already a disambig page - do we need Yellow (disambiguation) at the top, when there's already lots of disambig stuff on here? --Dangherous 08:45, 14 April 2006 (UTC)

Just move the dis-ambiguation info into the dis-ambiguation page and leave the color-related info here. Georgia guy 20:18, 14 April 2006 (UTC)

Ecru

Since this page redirects from ecru, it really should explain somewhere what the heck "ecru" is. — Johan the Ghost _seance 01:21, 2 May 2006 (UTC)

Agreed. The old page for ecru shows a discussion that they just refer to Wiktionary and then wiped it by replacing with a redirect. This is useless editing based on near religious views of what Wikipedia is supposed to be as opposed to a place of useful knowledge. There is far too many cases already where trawling through history files are necessary to unearth information. --19:49, 2 May 2006 (UTC)

OK, I've at least found out what the word means:

the light cream or beige colour of unbleached linen (OED)

This doesn't sound like any useful definition of "yellow", so we have the problem that anyone who comes here looking for "ecru" is going to be dumped into an irrelevant page. My opinion, therefore, is that we should redirect "ecru" to beige, which at least sounds very close (the definition of ecru includes "beige"), so that one article could reasonably handle both. We can then fold the old content of ecru into beige. Sound good? Anyhow, I've done it! — Johan the Ghost _seance 20:14, 2 May 2006 (UTC)

Your editing is a vast improvement over the redirection to yellow. Nevertheless I still feel a dedicated page for ecru (as well as for each and every one of the other colour names) are more useful, especially as separate colour pages offer(ed) a colour sample so non-native English speakers can actually see what is meant by names such as ecru. The current drive to eradicate detailed colour articles is therefore damaging to readers of Wikipedia. I hope someone of seniority can counter that destruction. And thanks again for your work, --11:41, 3 May 2006 (UTC)

Thanks for the positive feedback! As for your point, I sympathise. The objectors would say that Wikipedia is not a dictionary, which is true, but as you point out each and every colour article could contain a colour swatch, RGV and HSV specifications, etc., which is way more than you would get in a dictionary. However, this is something that needs to be decided, standardised and implemented across the board by WikiProject Color, so I suggest you go and pitch in there. It semes a little defunct at the moment, unfortunately. Wikipedia:WikiProject has some tips for stirring up interest in a project. — Johan the Ghost _seance 12:36, 3 May 2006 (UTC)

You are welcome. I followed up on your proposal and made a not at the talk page for WikiProject Color. Hopefully the pages can be resurrected before it is too late and hopefully before the release of Wikipedia 1.0 whose project indeed found colour descriptions of interest. --14:51, 12 May 2006 (UTC)

British Rail

British rail uses a special yellow on the front of their high speed trains to make theme more visible in foggy weather. Does anyone know the colour code. NCS (since its a reflective colour)or similar. DrNumLock 14:27, 24 January 2007 (UTC)

New York taxis

What is the wavelength of the color of New York taxis? Nurg 10:30, 12 July 2005 (UTC)

Hi, In this article it states that the first cabs with color yellow are from Chicago, but in the article "taxicab" it says that Harry N. Allen imported the taxis from France to New York and painted the taxi yellow... So, which one is it??? I would like to know because in the spanish version of this article (yellow) says that this practice started in New York, and I would like to fix if it really was in Chicago. Thank you!

Rubber Duckies

Is the best example of yellow "Rubber Duckies"? —The preceding unsigned comment was added by 82.47.15.195 (talk) 16:44, 5 January 2007 (UTC).

The beaks are orange too and the picture look somewhat orange from a distance. Quadzilla99 05:16, 16 February 2007 (UTC)

Yellow reflectance

I removed the spectral reflectance of yellow pic for a few reasons. Firstly, what information does this plot really give the reader? Why is the Y axis not labelled? Why would something which appears yellow also reflect equally well in green and red portions of the spectrum (and some in the purple region, its complementary color!) this can't be "pure" yellow. This is just more confusion the reader doesn't need to deal with. --Deglr6328 09:33, 4 Jun 2005 (UTC)

For an object to appear yellow it MUST reflect strongly in the red and green portions of the spectrum. Apparently the information that was in this figure is sorely needed. Dicklyon 19:20, 5 April 2007 (UTC)

Shades of yellow ... brown, green, orange, pink ... colour comparison chart

The shades of yellow colour comparison chart seems to contain a fair few colours which just don't seem yellow to me. It's full of browns, greens, pinks and oranges. I propose to remove these non-yellows. Note that the template {{shades of yellow}} has the same problem. J i m p 05:07, 5 April 2007 (UTC)

Who gets to decide where to draw the line? Dicklyon 05:55, 5 April 2007 (UTC)

Well, if it were up to me to decide where to draw the line ... ~~lines~~, I'd just have done so but, instead, I've brought it up here so we can all draw them together. J i m p 08:43, 5 April 2007 (UTC)

Are there any sources for these charts (not just the colours, but the arrangement and classification)? If not, they are original research, and need to be removed from everywhere. Notinasnaid 09:12, 5 April 2007 (UTC)

Not really "lines" either: it'd be more of a two-dimensional surface in a three-dimensional colour space but the point, of course, is who gets to draw it? Like Notinasnaid says, unless we can back such classification up, for any of us to start drawing it anywhere would be to be getting into original research. I don't think it would be that great a loss if these charts were removed. Jimp 16:21, 5 April 2007 (UTC)

Probably this discussion should be taken to the template talk page: Template_talk:Shades_of_yellow. As to where I would draw the line, perhaps a clear boundary colors like green-yellow, which would appear on both the green and yellow charts. Lime is definitely over that line, having more green in it than green-yellow have. Similarly define some boundary on the orange side. Dicklyon 19:18, 5 April 2007 (UTC)

I'd say we need a brown boundary &, by the looks of it, a pink one too ... if we're to keep any of the chart at all. There is a similar discussion at Template_talk:Shades_of_yellow#Not yellow which I've also brought up at Wikipedia talk:WikiProject Color#What to include as a shade. J i m p 20:11, 5 April 2007 (UTC)

Yellow is Red + Green

The Opponent process article says that there is no such color as reddish green, but this article says yellow is red + green. Anyone able to create an article that clarifies the difference between the color that the opponent process theory says there is no such color as and the color that yellow is in RGB?? Georgia guy 23:24, 11 April 2006 (UTC)

It's hard to understand what your confusion is here. Red plus green light makes yellow, not reddish-green. In the opponent theory, the red-green dimension is orthogonal to the blue-yellow dimension. Yellow is neutral in the red-green dimension; in this direction, red and green cancel, but you need red and green light to move up away from neutral along the blue-yellow axis. Dicklyon 04:54, 6 April 2007 (UTC)

Color comparison charts

I found the cleanup-laundryrack tag in blue and noticed that only blue and yellow had these big list of color stripes, duplicating the intent of the shades templates but with little maintenance or restraint. So I took them out. I also did some work to flush all occurences of lemon cream, a dup for the web color lemon chiffon that came in here the first time this laundry list of colors was started a few months ago. Anyone think we need such a list? Why? Dicklyon 16:27, 8 April 2007 (UTC)

The Color Comparison Charts display the shades of a particular color in approximate order of their shades (from the lightest at the top to most saturated in the middle to the darkest at the bottom) rather than in alphabetical order as in the Shades Template at the bottom of the article. The purpose of these Color Comparison Charts is to enable the Wikipedia user to more easily pick out a particular color which they may need for a particular use. For example, if someone is going to design a website, repaint a room, paint their house, or purchase a new automobile, they can look at the Color Comparison Charts and choose which color is best for or is closest to the color they need. It is much easier to do this when the colors are arranged in order of their shade instead of being arranged in alphabetical order. In addition, they display colors such as Crayola colors which may not be in the regular color articles and thus allow the user a greater selection of colors to choose from. I am restoring the yellow and blue charts with a short explanation as to their purpose and use. In the blue chart I removed colors that were objected to as too violet and in the yellow chart I removed colors that were objected to as too pink as well as the duplicate of lemon chiffon.

Yellow in human culture

Much of this doesn't seem to be relevant to colour yellow, but rather to how the word can be used. Would it be better if all of that were to be put on the disambiguation page? --pizza1512 ^{Talk Autograph} 06:49, 26 June 2007 (UTC)

Entries added

I added under the sexuality subgroup the referecence to yellow fever. I added the reference under the electronics subgroup regarding video composite connectors. I am about to enter the reference of CMYK to the see also section. I just wanted to know if all this is ok. Thanks.

Compliment

included both RYB compliment and RGB/CMYK compliment in order to match general pattern seen in blue and green color articles 72.152.53.127 19:55, 10 August 2007 (UTC)

Complementary color

The colorimetric complement of yellow is the color to add to make the mixture white. But that depends on the exact yellow chosen, and on the exact whitepoint chosen. It can be blue or violet, or generally in the wavelength range that stimulates primarily the S cones. I'll try to find a good source, since just stating that the complement is blue is a bit misleading. Dicklyon 19:07, 5 April 2007 (UTC)

As for that, we should use the standard yellow, 255 255 0, not a slightly greener color. The complement of violet is chartreuse. Georgia guy 17:14, 6 April 2007 (UTC)

Your coordinates only have meaning in the context of a prescribed colorspace, but in any conventional RGB colorspace the complement of that yellow is necessarily the blue primary (which may be violet in color, potentially), since [255, 255, 255] is defined to be white. However, there's no need to constrain the broad colorimetric description to an artificially limited color triangele, so I completely disagree with your point. Dicklyon 22:09, 6 April 2007 (UTC)

I found and added stuff about this. Dicklyon 16:27, 8 April 2007 (UTC)

color scientists actually agree that the complement of yellow light is blue, not violet. This has been accepted as a standard since at least 1861 when James Maxwell presented the first full-color projected image of a tartan ribbon to the Royal Institution. It is also the basis for all color photography, both chemical and digital- the additives being RGB and the subtractives CMY. Perhaps the confusion comes from the fact that painters and laypersons call blue light purple or violet, and really originally from the fact that Newton's attempt to compress the basic color spectrum into 7 primaries to match the musical scale has stuck with us English speakers to the present day. It is important to maintain the standardization of color nomenclature because of the difference in color words between languages (see Hunanoo)76.100.175.5 (talk) 20:05, 31 May 2008 (UTC)

Yellow--Jealousy?

I know green is related to jealousy but YELLOW!?--Editor510 ^{drop us a line, mate} 19:46, 28 June 2008 (UTC)

Without sources, it's pointless to argue; people can add whatever they want; in this case, however, there do exist sources for yellow representing jealousy. Dicklyon (talk) 01:45, 29 June 2008 (UTC)

Yellow Ninja (Motorcycles)

In section 5:15, transportation, it says that it is "well known" that a certain model of Kawasaki Ninja has "less aerodynamic drag" and somewhat more horsepower than other colors of the same model bike. While outside of my particular area of expertise, this sounds awfully fishy to me.

need to expand In minerals and chemistry sectio, see green article for analogy. Casliber (talk · contribs) 02:45, 23 March 2009 (UTC)

I've added a couple of examples that interested me to this section. There's another great pigment called "Indian Yellow", which is interesting because it was originally made from the urine of cows fed only on mango leaves (see this webpage). I'm dubious about using it, though, as I already added a pigment (yellow ochre) and it seems a bit thin with only one reference. Any thoughts? --RexxS (talk) 03:01, 28 March 2009 (UTC)

Bah - just realised there's a section called "Yellow pigments" - why isn't this a subsection of "In minerals and chemistry"? No wonder that section is short. --RexxS (talk) 12:15, 28 March 2009 (UTC)

I've expanded and sourced almost all of the pigment section, but I think the first image (File:Yellow spectra Abney 1891.png) really belongs with that section. However, the images are surrounded by {{fixbunching}} templates that I'm uncertain about disturbing. Can I get a second opinion on moving that first image, please? I'm also unhappy about the huge whitespace that shows between the "Electric yellow vs. process yellow" and " In minerals and chemistry" sections on my (admittedly widescreen) monitor. That would seem to be a result of the {{clear}} template used. Does anyone else see this as a problem? - and if so, can anyone with an eye for aesthetics suggest better layout? --RexxS (talk) 22:44, 7 April 2009 (UTC)

The fixbunching probably won't be needed if you move the image. Go for it. I'd also be happier without the clear and the resulting trapped white space. Dicklyon (talk) 23:12, 7 April 2009 (UTC)

I've made an attempt. Works ok up to about 1440 (as long as you show the contents) but gets progressively worse as the browser widens. Not good at all at 1920 width :( Revert it if you think it looks worse to you. --RexxS (talk) 23:31, 7 April 2009 (UTC)

Images

The changes made today by Tpbradbury make an improvement, I think. However, three points remain for me:

The PlanckianLocus image is too big at 300px for the surrounding text, and I'm tempted to scale it 260px (since the original is 1300px wide and an integer divisor usually produces slightly better results when resizing).
I also prefer a 45 em column width for references as 30 em produces two refs that run to four lines - that's too much, imho.
The Dongting Lake photo is beautiful (and yellow), but unless I'm missing something, it doesn't actually illustrate anything in the article. Should it be there?

Should we consider other images for the "In human culture" section? Those that come to mind are are the Mayan glyph (mentioned but not described: a good use of an image) and a cartoon image of the Beatles' Yellow Submarine (our younger viewers may not be familiar with it).

What do others think? --RexxS (talk) 16:31, 14 April 2009 (UTC)

In biology

I've added a line about carotenoids to the article. As far as I'm aware these are the only yellow pigments found in nature - I certainly can't think of any others. Comparing this article with green#Biology this might be a place to start on and then discuss other things. The list of species with yellow in their name is utterly pointless in my opinion. I saw there was mention of warning coloration (Aposematism) this should probably be included. I'd do more myself but I'm a bit busy atm. Smartse (talk) 16:37, 27 May 2009 (UTC)

Thanks - this was the sort of material I had hoped for, and yes, agree about lists of yellow thingies. Casliber (talk · contribs) 21:31, 27 May 2009 (UTC)

No problems, thought it was also worth asking the science reference desk to see if anyone there had any ideas of other yellow pigments: The question is here - as yet unanswered (which I suppose is a good thing!). Smartse (talk) 21:34, 27 May 2009 (UTC)

Curcumin is worthy of a mention and melanin (phaeomelanin) may be too. This has made me realise that often yellows are very dilute red and oranges. Don't know if there'll be a souce anywhere for that though. Smartse (talk) 12:57, 28 May 2009 (UTC)

Porn

In Chinese, porn movies are sometimes called "yellow films" (don't have a good source handy, but see this for example). Worth mentioning anywhere?

With respect to Asians (and by the way I am not ethnically Chinese), it should be clear that the term yellow has derogatory characteristics. As a more general note, it would seem to me that in English gold has a much more positive (up-market, regal, etc.) connotation than yellow (which also has connections with cowardice, illness, etc.)--达伟 (talk) 00:47, 13 March 2010 (UTC)

Questioning a deletion

Hello. I added a small (1 line) reference to International Yellow T-shirt Day, a cultural event that focuses on the colour yellow, with as a reference a link to a web page that covers that event. This was pretty much immediately deleted with the words "deleting an unsourced statement which doesn't add information about the color yellow". I would respectfully disagree with the assessment that it is not sourced, although if further sources are required they could be provided. As to "information about yellow", much of this article provides only cultural associations with the color, so it seemed in line with the spirit of the article. For example "Yellow Pages refers in various countries to directories of telephone numbers, arranged alphabetically by the type of business or service offered" which itself not sourced.

I am not that familiar with the etiquette of this type of discussion, but my post had sourcing as extensive as many other items in the article, and provided information about a real cultural event.

Could you please provide a more convincing reason for deleting this entry? I would have appreciated a note.

Thanks,

Fritiquoff

Fritiquoff (talk) 21:01, 30 March 2013 (UTC)

Of course, glad to respond. It as deleted because it seemed to be a promotion for an event that hasn't taken place, and whose importance wasn't clear. Why is this event important? How long has it been held? It seemed from the reference that this was not a serious event. Is this an event that would merit mention in an article on yellow in a print encyclopaedia or reference book? The yellow pages are mentioned because they are very commonly known and are like a cultural icon. I would suggest that you do an article about the day itself , in which you provide more information about it, and link it to the article on holidays. If you would like it to be in the article on yellow, please explain it more clearly in a way that is neutral and verifiable. SiefkinDR (talk) 19:23, 31 March 2013 (UTC)

Does yellow ever mean "slow down"?

The article includes this text:

In the rules of the road, yellow ("amber" in Britain) is a traffic light signal meaning "slow down," "caution," or "slow speed ahead." It is intermediate between green (go) and red (stop).

This seems wrong. In the US, where I drive, yellow certainly does not mean "slow down"; it means "the light is turning red; stop if you won't clear the intersection before it does." If you aren't stopping, slowing down will make the dangerous possibility of running a red light more likely. The speed limit remains as posted.

Is there some other context in which yellow does mean "slow down"?

Fixed.

I have never heard that yellow light means "slow down". I find the explanation a bit to specific on the use of yellow as a colour to signal meaning. To me Yellow lights and markings means: "Attention", "caution", or "beware". As red means "stop" and green "keep going" According to this yellow lights then signals "attention, the lights are changing" (from red to green or from green to red). —Preceding unsigned comment added by DrNumLock (talk • contribs) 20:33, 24 September 2007 (UTC)

Dlpkbr (talk)I know this was changed a long time ago, but the removal of the slowdown context because of a lack of context in the US is very US-centric. Here is the british commonwealth context: "A yellow signal means stop, unless you are so close to the intersection that you can't stop safely. A yellow signal indicates that the lights will soon turn red." —Preceding undated comment added 10:06, 28 July 2013 (UTC)

Starting the article with "Non-Metallic Gold /ˈjɛloʊ/ often mistaken by uncultured swine for the fictitious colour of yellow is the color of gold, butter and ripe lemons." is not in accordance with wikipedia standards. Encyclopedic articles should not contain personal attacks or derogatory language.

Why the image of the hand on yellow background?

Why has the image of the hand on a yellow background been placed in the montage? I don't believe there's any mention or explanation of it in the article. Is it really an important use of yellow in culture, history or nature? I think it should be replaced by an image of something more important discussed in the article.

Egg yolk isn't always yellow??

If my knowledge about this statement is correct; chicken eggs have a yellow yolk, but other eggs (e.g. ostrich, penguin, turkey, sparrow, eagle, many different bird species) might be white. Any bird species to be specific?? Georgia guy (talk) 18:53, 13 July 2016 (UTC)

Egg yolks

Depending on the hen’s diet, the yellow egg yolk may tend towards orange, but the general run of eggs in my local markets can easily be said to have yellow yolks. Tangentially, I think Michael Wilcox’s Blue and Yellow Don’t Make Green is relevant here. Just plain Bill (talk) 20:57, 7 October 2017 (UTC) p.s. In case my anecdotal observation is not persuasive, coloured like ripe lemons or egg yolks seems like a reliable source. Just plain Bill (talk) 21:28, 7 October 2017 (UTC)

Ok, my feeling is that the 'pedia has to be true and accurate. The statement "egg yolks are yellow" is demonstrably not. The statement does not state that we are talking about chicken egg yolks and my own observation is that many chicken yolks are more orange - this is why I reworded to the bit saying, " Many fruit are yellow when ripe, such as lemons and bananas, their color derived from carotenoid pigments. Egg yolks gain their color from xanthophylls, also a type of carotenoid pigment" - i.e. we are still identifying these things are yellow (and not saying them all to be yellow and adding some extra info about pigments, which is a core scientific note.

NB: See Wikipedia:Identifying_reliable_sources#Primary.2C_secondary.2C_and_tertiary_sources - tertiary sources are generally trumped by reliable secondary sources, FWIW. Cas Liber (talk · contribs) 22:25, 7 October 2017 (UTC)

We are discussing the indroductory section to a ‘pedia article on a primary color, not a legal document or a technical treatise on animal husbandry. In general terms, easily understood by a typical reader, egg yolks, raw and cooked, are yellow. Different hues may sensibly be called “yellow.” Lemon yellow tends toward the cool side, while many amber-colored egg yolks tend toward the warm side of the colors we call yellow. (Other yolks may be deep orange, or almost red, but NB the text in question does not say ‘’all’’ yolks are yellow, but that “yellow is the color of ripe lemons and egg yolks.”)

It has often been recommended that “hearing hoofbeats in Central Park, one should not immediately think of zebras.” Likewise when reading the intro to a general article about a color, one’s time will not be well spent immediately scrutinizing the text for neglected edge cases and exceptions not mentioned. The bulk color of some varieties of yellow ochre is tan, but artists successfully use it as a yellow pigment, and it works, in context.

Just plain Bill (talk) 15:58, 9 October 2017 (UTC)

Yes but no-one has to make any statement that is in any way inaccurate. This was behind my rewording above. It is a bit like the difference between "there are eight planets" and "the Solar system has eight known planets" or...whatever. We don't need to make any statements that are in any way incorrect because there is an art to making ones that cannot be misconstrued. Hence my rewording (which has been reverted a few times).

Yellow flowers

The latest research shows birds prefer red and bees blue or white. The yellow flowers often have ultraviolet patterns but the yellow is essentially irrelevant. See here Cas Liber (talk · contribs) 19:55, 16 October 2017 (UTC)

Needs a first sentence in lead

Per the MOS, the lead needs a first sentence which defines the subject and establishes notability. before the para on science and nature. Any suggestions? Cordially, SiefkinDR (talk) 07:03, 17 October 2017 (UTC)

The only person who keeps going on about notability is you. Material should be organised into related sentences so the lead flows (and not have random items in the first two sentences) and items should not be repeated. Cas Liber (talk · contribs) 14:07, 17 October 2017 (UTC)

Wavelength in lead

Why don't you leave out the specific wavelength from the lead? It's not necessary, because you've said it's between green and orange, and it's given in the infox just to the right, and its in section on optics in the article below. It's a technical term which is not understood by many readers. Also, there seems to be some disagreement on what it is; the info box gives a different wavelength. What do you think? Cordially, SiefkinDR (talk) 06:27, 19 October 2017 (UTC)

The wavelength is a key defining feature of what makes yellow light. Hence is a key part of the definition and needs to be included. I am not hugely familiar with optics so am not sure about ranking sources. Cas Liber (talk · contribs) 10:28, 19 October 2017 (UTC)

Monochromatic light of a single wavelength, unmixed with light of other frequencies, is seldom if ever seen in nature. It may be more accurate to define “yellow” in terms of perception, or in cognitive terms such as focal yellow, which is the narrow range of hues that the majority of people identify as the best example of a color called yellow. Focal colors have been shown to be consistent across languages, including those which do not have a name for a particular color. See Basic Color Terms: Their Universality and Evolution by Berlin and Kay. I am not keen on giving wavelength too much emphasis in the lead of this article. Just plain Bill (talk) 11:58, 19 October 2017 (UTC)

Ok point taken (that does look an interesting book), but do you think it is (for example) less notable than "According to surveys in Europe, Canada, and the United States, yellow is the color people most often associate with amusement, gentleness, and spontaneity, but also with duplicity, envy, jealousy, avarice, and, in the U.S., with cowardice."? Cas Liber (talk · contribs) 13:31, 19 October 2017 (UTC)

The lead does seem a bit wordier than it needs to be, and could stand to be pruned a bit. Just plain Bill (talk) 13:45, 19 October 2017 (UTC)

You both might think so, but the consensus across Wikipedia would likely be that for a 4049 word article it's about the right size. If it was significantly smaller folks' be adding to it. Question is, is anything more important not there. As well as anything really not so important there. Cas Liber (talk · contribs) 20:08, 19 October 2017 (UTC)

Possible removal from list

An entry in List of colors: A–F contained a link to this page.

The entry is :

Dark yellow

I don't see any evidence that this color is discussed in this article and plan to delete it from the list per this discussion: Talk:List_of_colors#New_approach_to_review_of_entries

If someone decides that this color should have a section in this article and it is added, I would appreciate a ping.--S Philbrick (Talk) 20:47, 17 August 2018 (UTC)

Yellow vs. Reddish-Green

Can anyone put into detail the answer to this question:

Why, even though yellow is not percieved by the human eye as a mixture of reddish green, does it have the behavior in RGB color theory as if it were such a color?? In the sequence R-O-Y-G-C-B-V, only R, Y, G, and B are percieved by the eye as primary colors. O is percieved as R+Y, C as G+B, and V as B+R. No color is percieved by the human eye as R+G or Y+B. Yet, in RGB color theory, R+G=Y. Georgia guy 23:11, 5 Jun 2005 (UTC)

Red and green is most certainly perceived by the human eye as yellow. You are mixing addition of colors with the multiplication of colors. While most people are used to adding pigments to eachother in art class (pigments absorb light and so mixing is multiplicative) they are not used to combining light sources (like light or with monitor displays).

The true "sequence" is RYGCBV, orange is a shade of red that is popular in european cultures. Many languages and people do not think of as anything more than a shade of yellowish red. Asteron ノレツァ 20:23, Jun 7, 2005 (UTC)

Well, what are the multiplicative primary colors?? The additive are red/green/blue and the subtractive are cyan/magenta/yellow. Georgia guy 21:02, 7 Jun 2005 (UTC)

Part of the answer to Georgia guy is that the colors we call "red" and "green" and use as "primary" colors in light sources don't exactly match the eye's cone cells. The response of the cones we call "red" actually peaks in more of an orangish yellow, and those we call "green" peak in more of a greenish yellow... with much overlap between them. The "processing" the eye does (in the "red-green coder") interprets the relative "signal levels" from "red" and "green" cones to derive the colors we perceive along the red-yellow-green part of the spectrum. Meanwhile, when we picked what we chose to call "primary colors", we picked colors which we could mix to provide the widest possible spectrum. Jeh (talk) 23:59, 9 December 2018 (UTC)

Why Do We Need A Wiki For A Color???

? — Preceding unsigned comment added by Aaron Justin Giebel (talk • contribs) 18:35, 29 April 2019 (UTC)

Mixture

According to the article

Yellow is the color of light whose wavelength is between 565 nm and 590 nm, or is a mixture of red and green light that appears to be the same color.

Red plus green is not the only mixture of light that will give you yellow. Orange plus lime should give you yellow too (a more vivid one at that). In fact there are an infinite number of possible spectral intensity distributions that'll give you yellow. It is true, of course that computers, TVs, etc. use red plus green to make yellow and this would be worth mentioning. The sentence needs rewording. - Jimp 1Jun05

Old Jeep?

Yellow could be the color of an old jeep.

Is there a significance that old jeeps can be yellow (as oppossed to, say, a Volkswagen Beetle)? If so, I think it should be explained in the sentence.

Associations and expressions -> Sports

The sentence "In cycle racing, the yellow jersey - or maillot jaune - is awarded to the leader in a stage race. The tradition was begun in the Tour de France where the sponsoring L'Auto newspaper (later L'Équipe) was printed on distinctive yellow newsprint." is not exact.

The "yellow jersey" is awarded to the leader of the overall classification in the Tour de France (and maybe others?), but not for all stage races (e.g. in "Giro di Italia" the leader's jersey is pink - actually for the same reason: the sponsoring newspaper "Gazzetta dello Sport" is printed on pink paper)
