replies: text: In RGB color theory, I always thought it was natural to think all colors whose coordinates have at least one 255 and at least one 0 are fully saturated. Do you see the difference between what I'm saying and what you're saying?? Georgia guy (talk) 21:28, 4 February 2014 (UTC)
replies: text: But are you referring to the RYB colors?  It doesn't work the same way.  It's hard to see how it works, since it claims to derive from Field, but his book only has three tertiaries (citrine, russet, and olive) and no quaternaries.  So I suppose it has been re-interpreted by Maerz and Paul; it will be a while before I can get back to my copy and check the referenced page, but I doubt that they provide a source for color coordinates, and it's also unlikely that the referenced RGB RYB converter is sourceable to a WP:RS.

color is not linear, it's logarithmic (just like sound leveling). redraw the spectrum and mixing ratios. for example a color "mid-between" color A and B doesn't mean that 50% of each (e.g. rose color is much near to red than magenta, though M-R is mixed 50-50. for spectrum, on horizontal axis, starting from red, every inch further, you need to "multiply" the frequency by a constant (10?). that's why there is "a lot of colors" between red to green and "just a negligible colors" from green to violet. and why red and yellow bulbs seem brighter than blue ones [with same characteristics]

replies: text: To say there is no difference between chartreuse, spring, and green is categorically false. While many people may have difficulty discerning between shades of green, I am certain that I could correctly identify them if put to the test. I would argue that the inability of some to differentiate green is partly biological, but also related to cultural and linguistic considerations as well as the limitations of sRGB displays in rendering the entire spectrum (only around 30%) with green being its weakest region. Most people just do not have experience thinking of green in that way. The breakdown of the spectrum is something that has evolved over time and follows a specific pattern across different languages and cultures. In Japan, for example, the distinction between green and blue as separate colors is a relatively new development, and red and orange are still not quite distinct. While there are names for both, they were/are considered "shades of red" in the same way that azure and blue are both considered "shades of blue" in most languages/cultures. In Italy, Russia, and Israel, however, azure is considered a separate basic color from blue rather than a shade of blue. Red usually develops first encompassing shades of orange and pink, followed by yellow and combined blue/green. Then the blue/green split comes. And so on and so forth with brown, purple, orange, etc. It is continuing to evolve today as cyan/teal/turquoise, for example, is becoming distinct from blue and green. I submit that Italians would do a lot better with the color switch test you proposed using blue and azure than a Canadian, for example, and that's not because they are biologically more capable of distinguishing or remembering, and Canadians wouldn't certainly would do worse because there is no difference between the colors, but because linguistically and culturally, they're used to thinking of them as different colors. Green does make up a lot more of the color space, and for that reason, I do agree that the halfway point between its secondary neighbors, cyan and yellow, is not the best place to set its tertiary neighbors. Perceptually, it is a bigger step from sRGB yellow to chartreuse than from chartreuse to green, and lemon lime is perceptually a better step between them. Idisestablish (talk) 03:35, 23 September 2019 (UTC)

text: It's because sRGB is not a linear scale. It's not because of limitations in display. The linear halfway point between 00 and FF would be BC. The non-linearity of sRGB is to make it more accurate in encoding darker colors, as human vision is more precise the darker the color. However, in the green/cyan/yellow/white plane, the colors are all bright and the gamma curve doesn't perceptually apply here, but each individual channel is still encoded in sRGB. 50% in sRGB is about 21.4% in linear scale, so chartreuse and spring are closer to green than to yellow and cyan.

thread_title:  hidden factor  

message: No sources are listed for the tertiary or quaternary RGB/CMY names. Where did these come from?
Aside from Orange and Violet, I've always seen intermediaries listed as "Yellow-Green", "Green-Cyan", etc. The quaternary ones are especially puzzling: vermillion, amber, lime, harlequin, erin, aquamarine, capri, cerulean, ultramarine, purple, cerise, and crimson.
I know these are general terms for the midpoints between the tertiaries, but what authority or standard declares them as official nomenclature? If these are just pulled from the X11 list, like "erin" being exactly midway between green and spring, then the article should say so. Otherwise, it should be stated that no standardized list of tertiaries and quaternaries actually exists.
Several other Wikipedia color articles suffer from similar issues. There's often no indication/reference of where exact numeric values are found for specific color names, aside from X11. 174.20.139.176 (talk) 03:15, 29 July 2018 (UTC)
replies: text: Yeah, I'd like to know where the names are coming from, as the cited source doesn't use them. Bumm13 (talk) 08:26, 27 November 2018 (UTC)

text: The only source I can find is from 2010, listing mostly the same color names distributed evenly across RGB hue angles: Per Bang's “color map with meaningful names”.  It is also referenced by Aubrey Jaffer’s “Color-Name Dictionaries”, which you can use to scan other color dictionaries (none have these “tertiary” dots evenly distributed along the boundary of the RGB gamut, except the Bang ones).

message: What Wikipedia claims to be RGB and CMY color wheels, isn't this hue scale actually from HSV/HSL, being equivalent to connecting specific six edges of the sRGB colorcube into a circle? 2A01:119F:21D:7900:E022:15ED:576A:3B51 (talk) 13:01, 11 August 2019 (UTC)
thread_title:  HSV/HSL 

message: It seems strange that this article is mostly focused on the RYB color space, which it mentions in the final section "has no scientific basis". It doesn't seem useful or necessary to include that color space's tertiaries, quaternaries, and quinaries. Nevertheless, if they are to be included the article should at least be consistent about what the RYB primary colors are. The first table in the Traditional painting section uses #ff000 for red, #ffff00 for yellow, and #0000ff for blue, as does the graphic labeled "A traditional RYB color wheel." However, in the following subsection the RYB primaries are #fe2712 for red, #fefe33 for yellow, and #0247fe for blue. This inconsistency is not only jarring, but makes this whole page much more confusing than it should be.
It seems strange that this page provides RYB primaries in the RGB color space when not even the RYB color model article does so. Can we simply remove the content related to the RYB color space from this article? Altay8 (talk) 23:07, 20 April 2020 (UTC)
replies: text: It isn't digital use that has made RBG (and CMYK) popular. Both are base on how human eyes work, because human eyes have red, blue, and green cone cells, activated by those wavelengths of light. It isn't so much that RYB has no scientific basis. It is that modern color science has found that red pigment and blue pigment of the traditional color model were the best approximations at that time to magenta and cyan, which provide a greater color gamut.

thread_title:  Tertertiary colour is not the same as intermediate colour 

message: I've removed the list of quinary colors as wp:or. Not only are the assignments of specific hue angles obvious OR, but even the existence of quinary colors in literature or even on the internet is mostly non-existent and therefore very wp:undue. Keep in mind that secondary (and tertiary, etc.) colors are purely a facet of traditional color theory and have no meaning in color science, so describing them quantitatively/scientifically (i.e. in a color space, like HSV) is mostly meaningless. I'm going to pick this article apart a bit more and likely boldly merge to secondary color. Curran919 (talk) 12:02, 15 February 2024 (UTC)
