Find Accessible Color Combinations: Contrast-A

Contrast-A allows users to interact with a 3-dimensional RGB color space to experiment with color combinations. Users can examine the color combinations under the aspect of accessibility guidelines and can create custom color palettes.

Contrast-A checks color combinations for sufficient contrast and displays the results according to WCAG 2.0 (Luminance Ratio) as well as the results according to older accessibility guidelines, WCAG 1.0 (Difference in Brightness and Color).
