Smart Color Contrast Ratio Checker - Testing Foreground Options for Backgrounds

Color Contrast Ratio Checker - Testing Foreground Options for Backgrounds

To check a Color pair, enter the foreground and background colors to test for compliance with WCAG contrast minimum ratios. The ratio is calculated, as well the compliance rating (No, AA, or AAA) for normal size, large text (18pt, or 14pt bold, or larger) and graphics (boxes).
This Fore-for-Back option includes a palette of 256 background colors for which you can test for an entered foreground/text color. There are other Options including Back-for-Fore and 4K colors

To see the Array of Compliant Colors, using the color palette, enter a foreground color to check with the background colors stored in the array. The list only shows pairs with contrast ratios >3. See About for more details.
