Creating high color contrast on your website is a key step on your accessibility journey. TPGi’s Colour Contrast Analyser (CCA) checks a contrast ratio and informs you if that ratio is accessible per WCAG standards. 1. Select a foreground and background color (either text or non-text) with the eyedropper tool, raw text entry or RGB sliders. 2. The CCA reports the contrast ratio, and a list of simple checkmarks indicates whether that ratio is WCAG AA and AAA compliant. The accuracy of the contrast ratio is aided by the fact that the CCA supports alpha transparency on foreground colors. 3. Also, try out the Color Blindness Simulator in the CCA to see how the colors you selected would look to a person who is colorblind.
