[edit] ...
'the CMY color model can more easily display a full gamut of colors than can RYB' - surely this statement is incorrect? No colour reproduction system working with a finite range of primary inks/lights etc is capable of reproducing a 'full' gamut. 87.81.240.78 12:16, 13 July 2006 (UTC)
[edit] ...
Under what article would one find quark color theory? Might be a good idea to link it here, possibly disambiguate.
- That would be quantum chromodynamics or color charge.

- Actually, one might add that to the contemporary theory section as one of the independent disciplines where new developments in color theory might arise. -SharkD 21:29, 26 October 2006 (UTC)
[edit] ...
Additive and Subtractive systems are NOT models. Please see Additive Color Subtractive color
[edit] Re:Merger
I'm firmly against the proposed merger of material from color circle. The color circle is a tool used in psychophysical research into visual perception, and has nothing to do with color theory, which is almost entirely connected with the arts. if it is to be merged anywhere, color circle should join color vision, not color theory. Grutness...wha? 14:24, 20 Jun 2005 (UTC)
[edit] Another opinion
Seconded, on the same grounds. One finds a color wheel in the theory of printing and in the theory of painting, with natural media - dyes and pigments, as well as with light on a computer screen. But one finds a color circle in psychophysics. A color wheel is concerned with creating the total perceived gamut, or the best possible approximations to it, as well as providing a rationale for a color scheme; whereas a color circle is concerned with spectral color and the mechanisms of perception. Need to disambiguate the two apparently similar terms, in the body of each article. - yoyo 29 June 2005 13:36 "(UTC)
[edit] Goethe and Newton
I believe the writer has confused Goethe and Newton - Possibly getting them exactly opposite. It is my understanding that Goethe increasaed the amount of green in his wheel. This addition was due to the preponderance of green in the natural world. Goethe tends toward four primaries with green as a primary - somewhat a mixture of light and pigment.
[edit] White light
"White light is composed of the mixture of the three primary hues red, green and blue."
No, white light is (usually) a continuous spectrum. A mixture of red, green, and blue light (that is, with sharp peaks at those frequencies) can produce a metameric match to white.
[edit] Color Basis
"On the other hand, any three (or four or five or six) real "primary" colors cannot mix all the colors in any medium, and this is always true no matter which "primary" colors are chosen and no matter which medium — inks, paints, dyes, filters, phosphors, artificial lights, or monospectral lights — is used to mix the colors. In other words, all mixable "primary" colors are incomplete or imperfect."
For the sake of accuracy, it should be mentioned that this occurs if we only consider a finite number "primary" colors. If we have a continuous range of frequencies that lie in the visible range, we con construct any color. This is how the world "produces" color; however, it is not practical yet to produce continuous spectras. This may seem obvious and theoretical, but this is a page on color theory, and this paragraph is discussing the limitations of color production in a general way. I think that saying "this is always true" is misleading.
[edit] Real Color Wheel
"Dark shades of yellow, oranges, and some reds are called browns by the Real Color Wheel." What, pray tell, is a Real Color Wheel? Seems to me it should either be linked to an explanation, explained in the article, or simply removed.
In fact, on further reading, it seems there are other sections as well that could use Wikifying. -Octavo 18:16, 30 June 2006 (UTC)
[edit] Edits 08.08.06
i concur with nearly all the points raised above, and i was generally alarmed at the inaccuracies in the previous article -- especially as it quotes my web site, handprint.com, as source for the information. i have completely rewritten the page, with apologies to the previous author, in an attempt to make it less inaccurate. more graphics would probably be useful, but i leave that for another time.
i think merging this page would be counterproducive. this topic is a pillar of artistic lore, and it forms a useful contrast to more developed theories of color perception and design necessary to use modern color media. Macevoy 00:32, 8 August 2006 (UTC)
[edit] HSL not mentioned?
I'm surprised that the HSL color model is not mentioned, as it is the most compatible with the idea of color wheels. In fact, I would find a discussion of Hue, Saturation and Luminence as being central to understanding the rest of the article. -SharkD 20:35, 26 October 2006 (UTC)
[edit] New image. Correct?
I had added this image to the 'Complementary Colors' sub-section, but removed as I'm not sure it's correct. What do you think? -SharkD 23:56, 16 November 2006 (UTC)
