Color, Contrast & Dyslexia Tools

Color and contrast are some of the easiest accessibility details to overlook, and this section brings together practical tools for catching those issues before they reach users. If you’re choosing text and background colors, Accessible Web’s browser-based checker offers a quick way to see the contrast ratio and whether your pairing passes WCAG AA or AAA for small text, large text, and non-text interface components. For a more hands-on desktop option, Colour Contrast Analyser lets you sample colors directly from the screen, paste in values, preview text and non-text contrast, and even simulate several types of color vision deficiency.

There’s also broader support here for teams looking beyond a single color check. Microsoft’s Accessibility Insights includes Chrome and Edge browser tooling plus a Windows desktop app, helping developers find common accessibility problems, inspect UI properties, check color contrast, and review coverage against WCAG 2.1 AA guidance. Together, these listings are especially useful when you want accessibility review to feel less abstract: they give you concrete contrast results, pass/fail guidance, and practical ways to inspect how an interface may work for more people.
