randoma11y.comSaved November 27, 2025
Summary
RandomA11y is a tool that generates random accessible color combinations and evaluates their contrast ratios to ensure WCAG compliance.
The tool displays foreground and background color pairings with real-time contrast measurements, helping designers and developers identify color combinations suitable for text and background elements that meet accessibility standards. Each combination shows contrast ratios in multiple formats (WCAG and APCA) to verify readability for users with low vision, aiming for a minimum 4.5:1 contrast ratio between foreground and background colors.
