Why is green 'Go' / 'Good'?

I came to article wondering why 'green' was selected as the 'go' signal for traffic lights, and more generally as an 'all is good' type status indicator. Can anyone help with a reference? —Preceding unsigned comment added by 203.6.223.18 (talk) 06:20, 19 April 2010 (UTC)[reply]


Topics from 2009

Green Dollar Bill?

In this article, there is an a picture of a dollar bill with a description under it that says that it is green. Obviosly it isn't green, it is black and white. How come? —Preceding unsigned comment added by 92.21.225.95 (talk) 19:23, 11 January 2009 (UTC)[reply]

The ink on the front is black, the ink on the back is green, and the paper itself is very light green. Since the picture shows the back, it's green and light green. — DanielLC 15:16, 1 April 2009 (UTC)[reply]

within-sight-of-the-finish-line peer review notes to go here...

Ok, let's see what we can do to get this baby over the line at FAC.... Casliber (talk · contribs) 10:54, 17 April 2009 (UTC)[reply]

  • I did wonder whether some more elaboration of germanic vs latin-derived names was worthwhile or just overkill in the Etymology and definitions section. eg names in german vs french/latin etc.
  • Green in astronomy - I know the B stars of Antares and Albireo have been considered green (the latter a highly regarded binary visually), and green is notably lacking in the star colours. Uranus has been described as green but I am not sure of other examples. I will ask the wiki-astronomers...Casliber (talk · contribs) 11:32, 17 April 2009 (UTC)[reply]
Wow, weird - woulda thought Wrad woulda known that one. Casliber (talk · contribs) 01:24, 18 April 2009 (UTC)[reply]
I did, but the problem is that they aren't sure if green actually had anything to do with it or if that is just a mistranslation of the name of the disease. Wrad (talk) 01:55, 18 April 2009 (UTC)[reply]
We have some stuff in the science section (uncited) about what might make a person turn green. Wrad (talk) 02:04, 18 April 2009 (UTC)[reply]
We can't just add everything we can think of that is green. That kind of stuff belongs at Green (disambiguation). This page is meant to be a description of what Green might mean and where it comes from. I don't think that the Berets or the Green line belong here. The Green Man might be good, but we already have an explanation of what Celtic culture thinks of Green, so it may be redundant. Wrad (talk) 02:00, 18 April 2009 (UTC)[reply]

Some comments

Some shithoughts after a quick look. --arsehoPhilcha (talk) 08:20, 18 April 2009 (UTC)[reply]

This article reflects a commitment to the thoroughly refuted "wavelength theory of color". All modern experts in the area agree that colors cannot be defined in terms of wavelengths since the present of so-called green wavelengths is neither necessary nor sufficient for the perception of green. Although refuted, the wavelength theory of color remains in circulation mostly by physicists. Physicists have a hard time understanding the psychology of color vision, believing naively that colors are "outside of the head". Modern psychology and neuroscience clearly shows that green is a type of mental/brain state, not a wavelength of light. —Preceding unsigned comment added by 72.130.188.19 (talk) 20:27, 3 January 2010 (UTC)[reply]


Coverage
Structure

Doesn't convince me, but I need to think about it, probably as things stike me in the individual sections. "Etymology and definitions" is a grab-bag. I've commented below on specifcs, but suggest the section should be dismembered and redistributed. --Philcha (talk) 08:20, 18 April 2009 (UTC)[reply]

Etymology and definitions
Color vision and colorimetry
  • Needs restructuring. Starting with colour-blindness looks odd. I'd go for: --Philcha (talk) 08:20, 18 April 2009 (UTC)[reply]
    • Wavelength range.
    • Additive & subtractive primary colours.
    • Normal human colour vision and sensitivity.
    • Colour vision defects in humans.
  • Need to explain "additive" & "subtractive" primary colours. --Philcha (talk) 08:20, 18 April 2009 (UTC)[reply]
  • "these are the peak locations of the rod and cone (scotopic and photopic, respectively) luminosity functions" is a waste of space, it's just jargon for what the preceding text explained. --Philcha (talk) 08:43, 18 April 2009 (UTC)[reply]
  • Colour vision in humans should mention blue-green deficiency, the 2nd most common, and that women seem to have better colour vision than men - genuinely, it's not just a fashion thing. Somewhere the article should commnent on our frequent use of red-green colour coding despite the frequency of red-green deficiency - traffic lights, warning / status lights, nav lights of ships & planes. --Philcha (talk) 08:20, 18 April 2009 (UTC)[reply]
    • I am personally red-green colorblind and can see traffic lights fine, so there isn't really an issue there. I've never heard of blue-green deficiency, though, so maybe that should be added. It's true women have better color vision, but I'm not sure that's as relevant here as it would be in Color blindness. Wrad (talk) 23:35, 12 May 2009 (UTC)[reply]
  • I sugest you research summmarise colour vision in animals. AFAIK primates are the only mammals w good colour vision, most others have restricted (e.g. cats) or no colour vision. IIRC in some S American monkey species all have a colour vision deficiency (can't remember which species or deficiency) and in some others it's common but not universal. To put mammal colour vision in perspective, IIRC some reptiles have 5 types of cones. How much you say about this depends on how much green figures in the literature on these topics. --Philcha (talk) 08:20, 18 April 2009 (UTC)[reply]
In minerals and chemistry
In biology
Western(culture)
Eastern(culture)
  • The use of "Asian" is lazy here - the Indo-Iranians were aso "Asian" but a completely different culture group, speaking Indo-European languages. IIRC the Thais are immigrants from S China, and IIRC Japan got the basis of its language and culture from China (? via Korea) but rapidly diverged because of its isolation. If sources support my recollections, the para should say e.g. "Chinese-influenced cultures". --Philcha (talk) 08:43, 18 April 2009 (UTC)[reply]
  • What does "In Ancient China, green was the symbol of East and Wood, one of the main five colors" mean? --Philcha (talk) 09:16, 18 April 2009 (UTC)[reply]
Nationality and politics
Military use
  • I'd skip Green Berets, but "Green Line" is commonly used. If the section has no other content, you could merge it into "Nationality and politics"
  • "the Green Line has been a term for demarcation between hostile territories in Cyprus, Israel, and Lebanon" needs a ref, which hopefully will also explain the origins of the term. --Philcha (talk) 09:16, 18 April 2009 (UTC)[reply]
See, I'd think they were both highly notable, but am happy to go with the flow on this one. Casliber (talk · contribs) 21:02, 20 April 2009 (UTC)[reply]
Notability isn't the issue, applicability is. It doesn't matter how famous they are or how many people know about them. What matters is, Do these things have anything more than a superficial connection to green? Do they add any meaning to the color? Do they add something to our understanding of what the color stands for? Are there sources to back these claims of meaning up? Wrad (talk) 23:48, 12 May 2009 (UTC)[reply]
Religion and philosophy

about that part has cited that GOD has worn a green cloth made of silk: its not god but they are good obedients those how succeeded to satisfy allah by thier deeds.therefore they will be awarded to stay in paradise for ever and enjoys the gifts given to them by god. god is greater than being made of matter or having body like what the creatures have or needing a place to live.god has created matter ,place, color and everything that u can imagine even ur mind. hence god is totally different form what have ever imagine. this what shia says.

Iran

"The flag of Hamas,[50] as well as the flag of Iran, is green, symbolizing their Islamist ideology."

The ignorant person who said that should be judged. Iran's flag had the green colour even during the era of our glory when it was our Lion and Sun in the middle of the flag. There was no Islamist ideology in Iran before 1979, the date a minority of Islamists took power by using sneaky strategies. The mentality of the people of Iran is to be pro-American and even pro-Bush : http://www.cfpdusa.org/news.aspx?type=Analysis&id=24 . The people of Iran even support a military action to change their regime !! So don't confuse the colour of our flag with this ugly regime. Thank you and God bless the one who changes the sentence ! (I can't do it ) —Preceding unsigned comment added by Basiscongo (talkcontribs) 18:12, 11 June 2009 (UTC)[reply]

The cited source, and several others that I checked, indicate that the green stripe honors Islam; this could well have been true before the revolution, too. Give us a source if you have one that says otherwise. Dicklyon (talk) 00:14, 22 June 2009 (UTC)[reply]

Could someone correct the flags map? It's missing Lebanon, which has a green cedar in its flag. Note that it would fall in the category "Other, most commonly to represent either lush national vegetation or heraldry" and not in "Islamic states using green". Eklipse (talk) 14:40, 14 July 2009 (UTC)[reply]

yea it would be in that section since the cedar tree is about natural vegetationIureor (talk) 09:16, 29 January 2010 (UTC)[reply]

Green info box looks blue.

The green chosen for the info box looks very blue to me, at least on my calibrated displays. I saw the PDF linked but am wondering why we should use that color for the main sample? To be honest, I still would like to move the color info boxes away from being about a specific color coordinate to being about the abstract color. PaleAqua (talk) 04:55, 17 May 2010 (UTC)[reply]

Well, we should get *some* kind of reasonable evidence before putting up any kind of hex coordinates or specific colors. A better thing might be to track down a copy of the 1976 book Color Universal Color Language and Dictionary of Names put out by the US National Bureau of Standards, and go by the most saturated in-gamut approximation at the same lightness/hue as whatever they define for each color term. Alternately, we could base the colors chosen on linguistic/anthropological research – there might be something useful on Paul Kay’s page. Instead, I used the CIECAM02 hue angle defined by that standard to be "unique green", along with a somewhat arbitrary lightness (I don't think there’s necessarily any reason to priviledge one lightness or another, but we could have a discussion about that). Either way, #00ff00 and friends cannot be acceptably labeled "green", etc., in my opinion. The sRGB specification is about making a useful color gamut for a high definition television standard, and has pretty much nothing to do with human color names, and the X11 color names were designed for displays with rather different characteristics than sRGB, by computer scientists making things up as they went along. The fact that these names are used on the web does not make them relevant to typical human color definitions. –jacobolus (t) 05:19, 17 May 2010 (UTC)[reply]
By the way, whether your display is characterized or not won’t make much difference, because web browsers do no color management of html/css colors; everyone is going to pretty much see a different color, even if all their displays are properly characterized. You need to take a screenshot and apply the sRGB color profile to it, to see what the color looks like in sRGB. –jacobolus (t) 05:21, 17 May 2010 (UTC)[reply]
Actually wasn't looking at the green in the browser but in a colorspace tool set to an sRGB profile, though it looks similarly bluish in my browsers as well. Just like #00FF00 is a bit yellowish to me. I think that the choice of any specific coordinate is wrong and other then giving approximate frequency / wavelength ranges we shouldn't go with any coordinates in the info boxes. I don't see how using the hue angle from CIECAM02 to create RGB coordinates is any better than using X11 colors. I'd rather actually add an entry with the reference 164.25 hue angle etc... PaleAqua (talk) 07:20, 17 May 2010 (UTC)[reply]
Okay; Part of that probably has to do with the quite yellow-green colors shown immediately below influencing the color appearance. Another part could be that there's extreme observer-to-observer variation in choice of "unique green": it’s unique for each person, but each person has his/her own. I'm going to try to write a bit of summary of what research I’ve read about that at unique hues, but it hasn’t happened yet. –jacobolus (t) 23:47, 19 May 2010 (UTC)[reply]

Have you ever taken a prism and focused a beam of sunlight through it? The color in the green part of the spectrum looks exactly like X11 Green. Also, if you check the color coordinates on the CIE chromaticity diagram on the outer edge just inside the horseshoe shape in the central part of the green part of the spectrum with your computer's digital color meter, you will see that it registers as the color #00FF00. The color you are attempting to foist upon us as "green" is really a medium saturated bluish green similar to the color emerald. Keraunos (talk) 05:47, 17 May 2010 (UTC)[reply]

The rest of this discussion belongs on Wikipedia Talk:WikiProject Color, so I’ve moved it there: Wikipedia Talk:WikiProject Color:. Keraunos (talk) 04:07, 24 May 2010 (UTC)[reply]

Can you copy the discussion back here as well, or revert it? It’s hard for me to follow exactly which bit goes with which if some parts are here and some are there. Feel free to add a disclaimer template pointing people to that page and suggesting they avoid further discussion over here, but in general discussion shouldn't be removed from a talk page. –jacobolus (t) 04:17, 24 May 2010 (UTC)[reply]

It's not that some parts are here and other parts there. I copied the whole section from where it says "green info box looks blue" so the part on the color project beginning at section 20 constitutes the whole of the discussion, includin g the part on this page. It simply didn't make sense to leave it here because it had morphed into a discussion about color in general, not just the color green. Keraunos (talk) 05:49, 26 May 2010 (UTC)[reply]

Secondly, can you remove all the extra section breaks you added to that discussion? It makes it really hard for me to follow –jacobolus (t) 04:18, 24 May 2010 (UTC)[reply]

o mlonger I think the section breaks are necessary because it is such a long discussion that it is hard to follow without the section breaks. If you want to change the titles of the section breaks, feel free to do so; I tried to make them as accurate as possible. Keraunos (talk) 05:49, 26 May 2010 (UTC)[reply]

Yeah, I think it's actually all okay; just temporarily slightly disorienting. –jacobolus (t) 02:44, 27 May 2010 (UTC)[reply]

The green info box definitely looks blue or cyan. We could just rename the article so it matches the info box, though. No big deal.  ;-) Daniel Quinlan (talk) 20:58, 21 October 2010 (UTC)[reply]

I couldn't agree more, but unfortunately, due to a lack of consensus, we are forced to accept an extremely idiosyncratic infobox green color. I don't consider it to be even the slightest bit close to a pure green, but, unfortunately, some insist on using a color other than green. I am still at a lost to understand why. It might not be so bad if the icon contained at least one color that came even a little bit close to being a pure green, but that is not the case. After having my own opinions being dismissed as being nothing more than idiosyncratic, I am no longer prepared to waste a lot of time on this issue. Good luck if you pursue this matter, because you will definitely need it once people start guestioning your sanity. VMS Mosaic (talk) 12:34, 31 October 2010 (UTC)[reply]

Esperanto

I think green is a color which Esperanto language associate itself with. Just look at their flag. —Preceding unsigned comment added by 178.90.25.134 (talk) 09:27, 12 February 2011 (UTC)[reply]

Meanings of green

Green could stand for the following: -Inexperience -hope -new life -immaturity -mediates between heat and cold and high and low -it is a comforting -refreshing human colour -it is the color of plant life -green with envy These can be use in compositions and essays. —Preceding unsigned comment added by Ningzailin (talkcontribs) 10:43, 30 April 2011 (UTC)[reply]

Edit request on 22 March 2012

From the "In Science" section:

{{clear-right}}
{{color swatch|#B05C94|Its complement<br>Munsell {{nobr|2.5RP 5/9}}}}
{{color swatch|#088C56|An example green<br>[[Munsell color system|Munsell]] {{nobr|2.5G 5/9}}}}

I'd like to see these two colors swapped. Putting the complement before the color it's a complement of doesn't really make any sense to me.
Prefered replacement:

{{color swatch|#088C56|An example green<br>[[Munsell color system|Munsell]] {{nobr|2.5G 5/9}}}}

Munsell Color Codes Edit Request: August 15 2012

I've checked with Munsell Color Company directly for the most dominant green color code, which seems appropriate to include in the table that appears in the first section of the article. A dominant Munsell Color Code for green is 5G 5/10 [Munsell Color Code 5G 5/10]. Edit would look similar to this:

| Munsell=5G 5/10 | Munsell=Munsell Color Code[1]

  1. ^ The Munsell Color System is a mathematical representation of one value code in the spectrum of green hues, based on the research of Albert Munsell, now at the Munsell Color website.
