App Description

Is your text readable for everyone? Find out in seconds.

Check foreground & background color combinations color contrast.

Contrast Ratio Checker is an accessibility tool for designers, developers, and anyone who cares about readable, inclusive design. Instantly check whether your foreground and background color combinations meet WCAG 2.1 standards — right from your phone.

Why contrast matters

Poor color contrast is one of the most common accessibility failures on the web and in apps. It makes content hard to read for users with low vision, color blindness, or anyone glancing at a screen in bright sunlight. WCAG (Web Content Accessibility Guidelines) defines exact minimum contrast ratios — and this app tells you, instantly, whether you pass or fail.

What you get

**Instant WCAG compliance results**

See your contrast ratio the moment you pick colors. Get clear PASS / FAIL badges for all four WCAG 2.1 criteria at once:
- AA Normal Text (≥ 4.5:1)
- AA Large Text (≥ 3:1)
- AAA Normal Text (≥ 7:1)
- AAA Large Text (≥ 4.5:1)

Live text preview:

See exactly how your text will look against the background — before you ship it.

Color vision simulation:

Preview your color pair through the eyes of users with Deuteranopia, Protanopia, Tritanopia, and Achromatopsia. Design confidently for everyone.

Accessible color suggestions:

Not passing? Tap Suggest and get automatically generated color variants that are guaranteed to meet AA — no guesswork, no manual trial and error.

Eyedropper / color picker:

Pick colors directly from your screen on supported devices — no need to type hex codes.

Save your pairs:

Save color combinations you use frequently and revisit them anytime.

Dark & light mode:

Fully themed UI that follows your system preference.

No account:

Open the app, check your colors, done.

Who it's for:

- UI/UX designers checking brand colors before handoff
- Front-end developers verifying CSS color combinations
- Android & iOS developers testing app themes
