Colour Contrast Analyser (CCA)

(4)4.5/5

TPGi’s Colour Contrast Analyser (CCA) is a free accessibility testing tool that checks if the contrast ratios on your website are WCAG compliant. This way, your website will be more accessible for customers who are colorblind or have low vision. To use, select a foreground and a background color with the beginner-friendly eyedropper tool or the more specific and technical raw text entry and RGB sliders. (The foreground color will be accurately measured because the CCA supports alpha transparency on foreground colors.) The CCA will then use the color data to determine the numerical color contrast ratio and if that ratio is WCAG AA and AAA compliant. This tool also includes a simple Color Blindness Simulator of the colors selected for testing. Achieve your digital accessibility conformance goals with TPGi experts, analytics, and solutions.
