How to edit and export cleanly

Use Color Blindness Simulator when you need to simulate how colors appear to people with different types of color vision deficiencies.

It is useful when you need quick conversions, contrast checks, palette ideas, or copy-ready values while designing.

Common use cases

  • Choose, check, or convert colors for an interface or visual asset.
  • Check whether text and background colors meet accessibility targets.
  • Convert between HEX, RGB, HSL, and related color formats.

How to use it well

  1. Start in the tool area above and enter the smallest complete input that represents your task.
  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 contrast for normal text and small UI labels, not only large headings.
  • Use color as a signal, but pair it with text, icons, or spacing when accessibility matters.
  • Save final colors in your design tokens so they stay consistent across the product.

Limitations to know

  • Color previews can vary by monitor, browser, and color profile.
  • Automated palette suggestions still need human review for brand fit and accessibility.
