Color contrast checker Contrast Grid. Built for designers and developers, you can check dozens of text and background color combinations against WCAG 2.0 accessibility minimums in seconds—no manual math required. Unlike single-pair checkers, it combines grid-based batch testing with visual pass/fail codes, so you can rapidly spot accessible and non-compliant pairs for digital products, branding, or UI palettes. Instantly view all results on one page, make edits on the fly, and export your grid for documentation or sharing. The straightforward web interface supports hex and named colors, offers sticky headings for large grids, and uses zero tracking for total privacy. Designers at top organizations trust Contrast Grid to ensure every color choice meets legal and usability standards, helping teams move faster with fewer errors and more inclusive results.
