How this tool helps
Check WCAG-style contrast ratio for text and background colors. It is built for quick browser-based checks where you need a clear answer, a copyable result, and enough context to review the output.
Inputs used
- Text color
- Background color
How to use Color Contrast Checker
- Start with the default example and run the tool once.
- Replace each input with your real value.
- Review the primary result and supporting result cards.
- Copy the result only after checking the assumptions and edge cases.
Example input
- Text color: #172018
- Background color: #fffdf4
How the tool works
This tool turns design inputs into CSS-ready or review-ready output so you can quickly test visual decisions before moving them into a design system or stylesheet.
How to read the result
Copy the generated CSS or color value, then test it against your real background, typography, and component size.
Best use cases
- Use Color Contrast Checker when you need a quick accessibility check before moving work into a spreadsheet, design file, CMS, app, or report.
- Use it to compare example values against your real inputs and catch obvious mistakes before sharing the result.
- Use the copy buttons when you need to move the output into notes, documentation, tickets, emails, or production drafts.
Common mistakes to avoid
- Checking a color outside the real layout context.
- Ignoring hover, disabled, and focus states.
- Using generated CSS without testing responsive behavior.
Limitations
Visual tools help with drafting and QA, but final design decisions should be tested in the actual product interface.
