This tool generates palettes that attempt to meet the WCAG 2.1 AAA Minimum Contrast Level requirements and the APCA Readability Criterion's Bronze Level requirements.

APCA (Accessible Perceptual Contrast Algorithm) is an experimental system for measuring color contrast that attempts to reflect human perception more accurately than the WCAG contrast ratio.

This palette-generator includes automated tests for conformance to the APCA and WCAG color contrast standards.
