I created this article simply separate to keep the article color from being over 32KB. However, it seems that color model is a separate re-direct to a different article. Any opinions on merging?? Georgia guy 19:10, 2 Jun 2005 (UTC)

I think that much of the information in this article belongs in the Color space article, and vise versa. But, no, I don't think they should be merged. -SharkD 15:36, 26 October 2006 (UTC)[reply]

"The cyan ink will reflect all but the red light, the yellow ink will reflect all but the blue light and the magenta ink will reflect all but the green light. This is because cyan light is an equal mixture of green and blue, yellow is an equal mixture of red and green, and magenta light is an equal mixture of red and blue."

I'm not entirely sure this is correct... You need less green intensity for the same amount of brightness on a screen. I seem to remember when programming color values for text display, that the ratios aren't 1:1 for mixed colors such as yellow and magenta. Of course this could have been an artifact of how the video card is programmed or the screens work (cost reasons dictating phosphor choice).

Just a question: This "The American Pantone and the German RAL commercial color-matching systems differ from the previous ones in that their color spaces are not based on an underlying color model." seems to me to require some checking. They say: "The structure of the RAL DESIGN System is not arbitrary. It follows an internationally used colour measurement system laid down by CIE (Commission International d´Eclairage) in 1976. The colour distances between the individual colours are defined by the CIELAB-colour distance formula. They are also embedded in DIN 6174." https://www.ral-farben.de/ral-design-aufbau.html?&L=1

Your link is to the “RAL Design” system introduced in 1993, which is not the RAL system referred to in this article, as you’d see if you looked at RAL (color space system). Cheers! –jacobolus (t) 17:57, 26 January 2010 (UTC)[reply]

There is one very confusing think! No clear distinction between color space and color model. Especually when there is talk about CIE color spaces. Are they color spaces, color models or both? 93.139.75.69 (talk) 13:29, 1 July 2010 (UTC)[reply]

It is not clear what are color models and what are color spaces. Especually CIE color spaces. Llike XYZ are color spaces or color models or they are both ?? —Preceding unsigned comment added by 93.139.75.69 (talk) 13:51, 1 July 2010 (UTC)[reply]

Actually, only “color space” has a technical definition according to the International Lighting Vocabulary published by the CIE. Color model, color space, color system, color solid, and similar terms are often used interchangeably and there's no agreed upon distinction between them. –jacobolus (t) 06:24, 2 July 2010 (UTC)[reply]

Tthank You wery much. Does that mean that there is no difference at all or that the difference (colr model-color space) is not clearyly explained or something else? Do You think that talking about color models does not have any sense? Or You are telling me that inside CIE there is no sense? Is it too much if I would ask You to sugest me list of CIE books or documents (beside one You allready mentioned) that would clear my dillema about usfulnes of color model concept. Thank You. —Preceding unsigned comment added by 93.139.93.243 (talk) 21:28, 2 July 2010 (UTC)[reply]

Forgive the intrusion. This entry into the subject is to my thinking too brusque. It needs to be introduced more. Colour is a non-trivial subject area and needs to be trated as such. Non-expert people will be primary users and need to be treated as such, i.e. as much hand holding as possible. This entry into the article is brusque. — Preceding unsigned comment added by Juliusguzy (talk • contribs) 01:40, 7 March 2012 (UTC)[reply]

Spherical coordinate system

I created three images comparing the internal cross sections of several color models described in the article, plus a fourth image showing the regular spherical coordinate system for comparison. I'm not sure if they can be used anywhere in the article, however. ➧datumizer  ☎  03:41, 2 October 2018 (UTC)[reply]
