How to edit and export cleanly

The Color Contrast Checker compares foreground and background colors so you can judge text readability and accessibility.

It is useful for buttons, labels, links, badges, charts, and dashboard UI where color choices affect usability.

Common use cases

  • Check text and button colors against accessibility targets.
  • Compare brand colors before using them in UI components.
  • Document approved color pairs for a design system.

How to use it well

  1. Enter or pick the base color values.
  2. Adjust the options such as format, contrast target, scheme, or gradient direction.
  3. Review the generated preview and numeric values.
  4. Copy the color values into your design file, CSS, or documentation.

Practical tips

  • Check normal text separately from large headings because requirements differ.
  • Do not rely only on color to communicate status or errors.
  • Test hover, disabled, and selected states as well as the default state.

Limitations to know

  • Contrast formulas do not judge brand fit or visual hierarchy.
  • Real readability also depends on font size, weight, spacing, and display quality.
