Legacy Visual Contrast Wiki for Silver/WCAG 3

This page has been broken up into subpages to help organize topics.

Visual Contrast Whitepaper in progress on readability contrast and related design theories. This page contains selected research notes of A.Somers' vision and contrast research to be made into a whitepaper in support of Silver/WCAG 3.
An Advanced Contrast Prediction Model This specifically discusses the APCA perceptual contrast prediction model, including the math and code samples.
Visual Contrast Conformance Model This is the former talk page relating to the multi-score conformance model for Visual Contrast for Silver/WCAG 3.
Resources: Glossary, Bibliography, and links to team member materials. Includes a lighter side section and additional designer examples and guidance.
