How many colors do I need?

Most design systems use 6-8 colors plus 5-7 neutrals. Each color needs light and dark variants. Quality over quantity \u2014 fewer accessible colors beat many inaccessible ones.

Can I use my brand colors?

Usually yes, with adjustments. If your brand blue fails contrast, create accessible tints and shades. Use the brand color for decorative elements and an adjusted version for text.

What about colorblind users?

Beyond contrast ratios, avoid relying on color alone for meaning. Use icons, patterns, or labels alongside color. Test your palette with a color blindness simulator.

How often should I re-test?

Re-test after every palette change and during each design system update. Automated contrast testing in CI/CD pipelines can catch regressions.
