Sapc Apca
⭐
352
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.
Apca W3
⭐

The APCA version, to be licensed for use with guidelines: W3/AGWG.

A11y Color Contrast
⭐
14

⭐
13
Choose the boldest and most accessible color for a given background.
Deltaphistar
⭐
11
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).
Bridge Pca
⭐
9
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.
Contrast Grid
⭐

App for contrastgrid.com
Myndex
⭐
6
