Color Blind Palette Generator

Why Color Blind Friendly Palettes Matter

Think about the last chart, dashboard, or infographic you created. Now imagine that 8% of your male users and 0.5% of your female users might struggle to distinguish the colors you carefully chose. That's the reality of color vision deficiency—and exactly why accessible palettes matter.

A thoughtfully designed color palette ensures your message gets through regardless of how someone perceives color. This matters everywhere color carries meaning: data visualizations, status indicators, navigation systems, and beyond. Testing your palette early catches problems before they become expensive fixes—or worse, before they confuse your users.

How This Tool Helps Designers

This generator tests your palette against all four major types of color vision deficiency: protanopia, deuteranopia, tritanopia, and achromatopsia. The live simulation shows you exactly what users with each condition see—no guessing required. Meanwhile, the built-in contrast checker flags any combinations that don't meet WCAG standards.

The daltonization feature is particularly useful—it suggests adjusted colors that improve visibility for color blind users without throwing off your entire design. And with the context previews, you can see your colors in action on buttons, cards, and charts before committing to anything.

Tips for Choosing Accessible Palettes

Start by prioritizing contrast. Adjacent colors in your palette should have at least a 4.5:1 contrast ratio for normal text (3:1 for large text) to meet WCAG AA standards. Don't rely on color alone—pair important color-coded information with patterns, icons, or labels as backup.

Run your palette through all the simulations before you finalize anything. Like a color? Lock it. Need to regenerate the rest? Go for it. Once you've landed on something that works across all vision types, export it in whatever format fits your workflow—CSS, Tailwind, JSON, you name it.
