Myndex/SAPC-APCA
APCA (Accessible Perceptual Contrast Algorithm) is a new method for predicting contrast for use in emerging web standards (WCAG 3) for determining readability contrast. APCA is derived form the SAPC (S-LUV Advanced Predictive Color) which is an accessibility-oriented color appearance model designed for self-illuminated displays.
Myndex/deltaphistar
𝜟𝜱✴︎ or Delta Phi Star is a variant method of determining lightness contrast, and a sibling of APCA and SACAM. It is a simplified version using easily invertible standardized maths, however it lacks some useful properties such as polarity sensitivity. In fact, it is intended for applications where a "general" simplifed perceptual contrast is desired, where polarity sensitivity is not needed (or is ambiguous).
reiniiriarios/chromaticity-color-utilities
:art: Color utilities for Node.js. Conversion, modification, and color schemes of: RGB (at any bit depth), HSV, HSL, HSI, HSP, CYMK, YIQ, XYZ, xyY, L*a*b*, L*u*v*, Y'PbPr, Y'CbCr, and more.
Myndex/seelab
sRGB parsing and processing RGB data in and out of CIE XYZ, xyY, LAB and LUV, and more!
pex-gl/pex-color
Color utilities (css, rgb, hex, hsl, hsv, hwb, lab, xyz, okhsl, okhsv, oklab, hpluv, hsluv, lchuv, bytes) for PEX.
Myndex/seestars
See Stars is a Myndex MicroColor Library. This has standard functions for the standard (piecewise) IEC conversion of sRGB to Y, and the CIE standard Y to L* (Lstar) and back again. The math & constants here reference those of CSS 4 for compatibility.
