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.

Myndex/TurboContrastulator
For a number of years now, work has been proceeding in order to bring perfection to the cryptically conceived concept of contrast that would not only supply inverse reactive spatial quanta for use in unilateral phase detractors, but would also be capable of automatically syncing cardinal grameters. Such an algorithm is the Turbo Contrastulator.
