message: Hi. I've been worked in the List of palettes series of articles, and I found that the base article about computer palettes was a stub. Now it is expanded and clarified; I hope there were no (much) more "Indexed color" vs. "Palette (computing)" wars in future. And... I know, it still lacks references... -Ricardo Cancho Niemietz (talk) 19:05, 19 February 2008 (UTC)
thread_title:  Article enterely rewritten 

message: There is no 'colour palette' page, but there 'should 'be. Colour palettes are created in many areas of design & art (the visual arts), not only a computer graphics context. Eg
Architecture, Interior design, Jewelry, Product design of many kinds, Animation, Fine art, Illustration, Print, Textiles, Branding & Brand identity, Clothing, Publishing & Magazine design, Graphic design in non-computer contexts inc advertising, Craft, Outsider Art, Graffiti  ....
Predicting colour palettes is a big area of trend prediction (an industry), and creating colour palettes can be a job role in itself. The term 'colour palette' should not link to here, which is a subtopic. Not sure how to undo it though. http://en.wikipedia.org/wiki/Color_chart is a better re-direct than this page
The omission of the 'colour palette' page is a big lack for wikipedia, but typical of wikipedia inconsistency.  EE 90.194.24.158 (talk) 12:40, 10 September 2014 (UTC)

thread_title: Assessment comment

message: I agree it's not unusual to associate a palette with a CLUT, but it's not universal.  See for example this book which says "Palette. The available colors in a colorspace or specific image. In 24-bit RGB images, the palette is the number of colors it is possible to represent, which is 16.7 million. In indexed-color images (such as GIF) the palette is a fixed set of colors written into a CLUT (Color Look-Up Table)."  I edited the lead to be a bit more general, but got reverted.

replies: text: Well, the thing is, this article is about CLUTs. Calling the colors in a colorspace a palette, while it may be acceptable in a loose, informal sense of a palette being a set of colors, technically speaking it is just wrong. For one, RGB 888 is a color format, not a palette. Other uses of the word "palette", while valid, have their place in the other articles mentioned in the hatnote. --uKER (talk) 02:02, 15 June 2020 (UTC)
replies: text: Well, someone made it about CLUTs, but some earlier versions included the more general interpretation of a palette as I described.  Check it out. Dicklyon (talk) 04:43, 16 June 2020 (UTC)
replies: text: The thing is, different definitions of a term are supposed to go into separate articles. That's what disambiguations are for. --uKER (talk) 04:51, 16 June 2020 (UTC)
replies: text: I'm not talking about a different definition, but about the set of available colors.  The other topic, a tool palette, was sensibly moved elsewhere, I think.   Even small 3-bit and 4-bit palettes were done without CLUTs, yes? Dicklyon (talk) 05:35, 16 June 2020 (UTC)
replies: text: I don't know what 3-bit or 4-bit palettes you're talking about, but any time the colors have preassigned numbers without the number being a description of the color's components (be it RGB, CMYK, HSL, YUV, YCbCr or whatever), then it is a CLUT. --uKER (talk) 23:48, 20 June 2020 (UTC)

text: Here are two definitions that sum up pretty much everything: . It basically says that CLUT is a kind of data compression approach for image data. A sprite just maps (associates) pixels (R256,G256,B256) into (with) indexes of a single table of colors which is shipped with the sprite and which is loaded into CLUT upon rendering. That's how it works. AXONOV (talk) ⚑ 18:18, 28 August 2022 (UTC)
replies: text:  I don't think there's any ambiguity or misunderstanding of what a CLUT is, just whether a palette necessarily is (or involves) a CLUT.  Early 3-bit color systems, for example, would drive each of R, G, and B directly from a bit of the 3-bit color code, without any intervening lookup or logic.   And 4-bit color systems like the Commodore Vic similarly drove the color bits, possibly with a bit of logic, through a few resistors that controlled phase shifters to make NTSC or PAL color signals; no intervening lookup, just a fixed palette with a structure determined by the color modulation hardware. See this note, which starts with "The C=64 (with its VIC-II chip) features a palette of 16 colors." and derives a CLUT that can be used in emulators, but makes it clear that the VIC-II hardware had a fixed palette and no CLUT.

text: Also, as I noted at the outset, a 24-bit color system (or a 5+6+5-bit RGB color system, and other variations) has no CLUT still has a palette. Dicklyon (talk) 19:17, 28 August 2022 (UTC)
