GLSL-Color-Functions

Color space conversions, metrics, and other utility functions for color in GLSL.

Still very much a work-in-progress! If you see anything wrong, please let me know (or make a new branch if you're feeling nice).

Currently Included:

Color Spaces:

• XYZ
• sRGB
• RGB
• L*a*b* (CIELAB)
• LCh (CIELCh)
• P3 Display
• sYCC (sRGB's official YCbCr space)
• OkLab

Other:

• A (proper) implementation of CIE Delta-E 2000
• Color from temperature (cubic approximation) and temperature from color (McCamy approximation)
• Lightness / Luminance / Luma functions
• D65/D50 white point option for RGB<->XYZ and L*a*b*<->XYZ

Planned (descending priority):

• OkHSL/OkHSV
• Chroma/Hue getter functions
• Delta E CMC
• Color temperature adjustment
• Interpolation wrapper functions
• CIELUV
• Gamut mapping?
