Color Contrast Checker for Website Accessibility
Make your website easier to read for every visitor. Use this free color contrast checker to see if your text, links, and background colors meet common accessibility guidelines.
You do not need to be a designer to use this tool. If you can copy and paste a color code, you can check your contrast and improve readability in just a few minutes.
How to Use the Color Contrast Checker
This tool compares your text and background colors and tells you if they pass common accessibility targets based on WCAG contrast ratios.
- Copy your color values (for example, HEX codes like
#1A1A1Aor#FFFFFF). - Paste them into the text, link, and background fields below.
- Choose your text size and review the results for both text and links.
If your colors fail, try a darker text color or a lighter background until the result shows a pass.

What This Contrast Checker Tests
The checker uses contrast ratios to see how clearly your text and links stand out from the background.
- Readability: How easy the text is to read on your background.
- Contrast ratio: A score based on the brightness of both colors.
- Accessibility targets: Results aligned with common WCAG AA and AAA goals.
- Light and dark pairs: Works for light text on dark backgrounds and dark text on light backgrounds.
If you prefer British spelling, this tool works the same as an accessibility colour contrast checker.
What Counts as Good Contrast
Most body text needs stronger contrast than large headlines. As a simple rule, start by making sure your normal paragraph text passes first. Headlines and big buttons are easier to adjust later.
If your brand palette is very light, try darker text or a deeper accent color. Small changes in tone can make a big difference in comfort and clarity.
Practical Tips for Accessible Color Choices
Start With Your Main Text and Background
Run the checker on your main body text and page background first. This sets a strong base for the rest of your design.
Check Buttons, Links, and Alerts
Buttons, links, and alert banners need high contrast for text, borders, and focus states. Test your button text, hover colors, and link colors so they are easy to see and click.
Plan for States and Overlays
Many issues show up in hover states, disabled states, or image overlays. Test those colors too so your content is readable in every state, not just the default.
Common Questions About Color and Accessibility
Is this an ADA compliant color checker?
Yes. While people often say “ADA compliant,” the results are based on contrast ratios used in common WCAG accessibility guidelines. You can use this tool as your ADA compliant color checker for text and basic UI elements.
Can I use this without design experience?
Yes. The page is built for any user. If you can copy and paste color codes, you can use this color contrast checker without design training.
Does this work as a website color accessibility checker?
It does. When you paste in the colors from your site, you are checking website color accessibility. It is useful for new builds and for refresh projects.
What if my brand palette is very light?
Try darker text, stronger outlines, or a deeper background behind key text. As colors separate more, your readability scores will improve.
What about “accessibility colour contrast checker”?
Same idea, different spelling. If you search for an accessibility colour contrast checker, this tool still meets that need.
Why Contrast Matters for Everyone
High contrast helps people with low vision and color-vision differences. It also helps users on mobile devices outdoors, older screens, and in dim rooms.
When you choose colors that pass this contrast test, you make your site more comfortable and effective for every visitor, not just a small group.
Make Contrast Part of Your Design Process
Use the Checker Early
Add this color accessibility checker to your design checklist. Test your core color pairs as soon as you choose a palette.
Test Components, Not Just Pages
Check buttons, cards, alerts, banners, navigation, and footers. Small fixes now can prevent bigger rework later.
Retest After Changes
When you change fonts, weights, or sizes, run the checker again. A small shift in style can affect readability.
