ARC
ARC • APCA Readability Criterion — a set of web-standard guidelines for text and non-text for use with the APCA contrast algorithm. Latest published version at this link:
apca-w3
The APCA version, to be licensed for use with guidelines: W3/AGWG.
bridge-pca
A simplified version of the APCA math to bridge from WCAG_2 contrast math to the future, while being 100% backwards compatible with WCAG_2 contrast. By "backwards compatible" we mean if bridge-pca passes it, it will automatically pass WCAG_2 contrast.
colorparsley
A lightweight but versatile mini-lib to parse color strings, objects, or numbers, returning a simple rgba array, and related string utilities. This was developed as part of the basic APCA distro.
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).
fancyfontflipping
Fancy Font Flipping is a demo I first put up in CodePen to illustrate the issues with flipping the text color from black to white based on a given estimated background luminance.
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.
