Contrast-A allows users to interact with a 3-dimensional RGB color space, experiment with color combinations, check the contrast according to both WCAG 2.0 and 1.0 and see the results for different types of color deficiency. Custom color palettes can be created, printed and saved as Pdf to the user's desktop.

Colour Contrast Check
by sebastien
& 26 others
The Colour Contrast Check Tool allows to specify a foreground and a background colour and determine if they provide enough of a contrast "when viewed by someone having color deficits or when viewed on a black and white screen"[W3C].
The tool will indicate that the colours pass the test if both the colour difference and the brightness difference exceed their threshold. It will indicate that it sort of passes if only one of the two values exceed their threshold. And finally, it'll fail to pass if neither value exceeds its threshold.
