Talk:List of color spaces and their uses

Inclusion of color models

Any views on why this article includes RGB and CMYK, which are color models, rather than specific color spaces? Notinasnaid 10:13, 12 January 2007 (UTC)

My view is that this article has generally little purpose. --jacobolus (t) 20:36, 20 September 2007 (UTC)

CIELUV

I'm not convinced that CIELUV can be replaced by CIELAB they have different advantages and disadvantages. And why is there no article on this? —DIV (128.250.204.118 04:16, 30 July 2007 (UTC))

I've amended the relevant sections, with reference. — DIV (128.250.204.118 07:50, 15 August 2007 (UTC))

Feel free to help out at Lab color space, and join the discussion at Talk:Lab color space. Also note that a CIELUV article was added; it should certainly have a better comparison to CIELAB than it does now. --jacobolus (t) 20:36, 20 September 2007 (UTC)

storage&display versus pickers

To me, the main problem in those articles about color spaces are the confusing of where the model take place in softwares. << HSL and HSV (also called HSB) are two related representations of points in an RGB color space >> [cf. HSL and HSV] False!! What the RGB is doing here? HSL and HSV are representations in their own space, in physical color space, or in what you wan't. Their is at the first step no link between color models. Models are not created inside models. But the screen device is in RGB, this is this device that make us make the conversion. Now about softwares, many have various color picker models. But about no one have many display color spaces or storage color spaces. For exemple, you pick up color in the HSL model but you use them on a RGB raster so you don't use any of the HSL specificities. For example, you light a color to white and unlight it, it turn gray because the display is in RGB and it doesn't matter that you have choose your color through a HSL color palette. Actually is there softwares that use HSL for display and storage? RGB and CMYK are color spaces that have a direct physical usage, screen and paper. a true HSL display could enable a different (better?) way to manipulate lights and saturations. And to not loose datas, their should be a file format to store HSL. True that a "HSL pixel" should take more memory space than a RGB one. Lacrymocéphale

add more spaces

Please add information for:

• CIE-based: CalRGB, CalGray, Lab, ICCBased.
• HSLuv, a human-friendly alternative to HSL: http://hsluv.org/ — Preceding unsigned comment added by 5.28.87.197 (talk) 11:04, 22 July 2018 (UTC)

HSL and HSV

Quote: "(hue, saturation, lightness/luminance), also known as HSL, HSI (hue, saturation, intensity) or HSD (hue, saturation, darkness), is quite similar to HSV, with "lightness" replacing "brightness". The difference is that the brightness of a pure color is equal to the brightness of white, while the lightness of a pure color is equal to the lightness of a medium gray."

This is not accurate at all. A perfectly "light" color in HSL is pure white, not gray; and a perfectly "bright" color in HSV is... something I can't really explain. It has to do with the result of shining a super bright white light on an object. I.e. shining a super white light on a red object causes the object to still appear red, just brighter or more intense. But it's not white. SharkD  Talk  05:43, 10 March 2017 (UTC)

Never mind. I understand what the original author was trying to say now. SharkD  Talk  15:48, 13 March 2017 (UTC)

Cylindrical color models

HSL and HSV shouldn't really be mentioned in this article. They are color models, not color spaces. I.e. any RGB color space can have a cylindrical color model applied to it. There are even cylindrical versions of CIELAB and CIELUV in the form of CIELCH_ab and CIELCH_uv. At the very least these color models should be placed in their own section and mentioned at the same time. SharkD  Talk  05:50, 10 March 2017 (UTC)

I created a "Cylindrical transformations" section and merged that stuff there. SharkD  Talk  06:15, 10 March 2017 (UTC)
