The following chart displays foreground/background colours combinations that pass WCAG 2.0 AA accessibility contrast checks. Combinations marked 'Y' pass for all font sizes, while combinations marked '18' are only valid for text larger that 18pt. Accessbility tests based on this Colour Contrast Check tool - clicking individiual combinations in the grid below will take you to the test results for that specific combination.
