merge from value
These describe the same color attribute, and "lightness" is the term which is coming to be used in modern models like CIELAB and CIECAM. The value article should be merged into this one, and then redirected here. --jacobolus (t) 20:02, 19 September 2007 (UTC)
Value is an extremely relevant term in drawing and painting, and it shows no signs of falling into disuse. I believe "lightness" has more industrial connotations, whereas "value" still applies to the fine arts. -bornon5, 31 October 2007 —Preceding unsigned comment added by Bornon5 (talk • contribs) 02:53, 1 November 2007 (UTC)
- That's fine. The article can explain that both words are used for the concept, and the value article can redirect here. The point is that we have a single concept, so it's silly to duplicate the information about it on two different articles. The popularity of the term "value" comes mostly from Munsell's use, as far as I know. More recent models like CIELAB and CIECAM02 use the term "lightness". --jacobolus (t) 04:24, 1 November 2007 (UTC)
- Comment. Is the term value used in painting to mean something not covered in the value article? If we mean that lightness=value=correlate of perceived brightness, I'm for merging them.--Adoniscik (talk) 14:58, 3 February 2008 (UTC)
What is the diagram?
Some problems with the previous version
"Various color models have an explicit term which places the color on a scale from utter black to pure white. The HSV color model and Munsell color model have an explicit value, while the HSL color model uses a related parameter called lightness instead."
The "explicit value" of HSV refers to something different; i.e. the value/color is not "on a scale from utter black to pure white." The HSL parameter lightness is the one that's closer to the Munsell system.
"In the HSV and Munsell color models, a color with a low value is nearly black, while one with a high value is the pure color."
This is not true of the Munsell system. HSV is the oddball here. It also contradicts the first sentence I quoted.
As for the rest of the article, it was in need of cleanup (forming paragraphs out of loose sentences, etc.) You were right in that I deleted a good bulk of stuff on accident. SharkD (talk) 06:19, 29 June 2009 (UTC)
- Further, in the image, it might be a good idea to put the word "luminance" somewhere on the x-axis. It's explained in the caption, but it might not be enough. SharkD (talk) 06:33, 29 June 2009 (UTC)
Tone (disambiguation page) links to Lightness (color), but the article never uses the word "tone", and I don't think they're at all synonymous. Anyone care to clear it up? —Pengo 12:12, 20 July 2009 (UTC)
- Tone is a term that was traditionally used in black-and-white photography for this concept, at least since the early 20th century. See tone mapping (not a great article, but a start). Or here is an old book example. And here is one that compares "Tone" to "Value" explicitly. Dicklyon (talk) 14:52, 20 July 2009 (UTC)
- Also Tone reproduction is more about the traditional use in photography. Dicklyon (talk) 18:41, 20 July 2009 (UTC)
