Comparison
Khroma vs ColorUI
Khroma uses a neat onboarding: pick 50 colors you like, and it trains a personal ML model that only suggests colors in your taste. ColorUI takes a different path with a free prompt-based AI generator that needs no onboarding and produces palettes tuned to project context.
When ColorUI wins
- You do not want to spend 10 minutes labelling 50 swatches before generating anything.
- You need accessibility (WCAG, APCA, color-blind fix) on the same surface.
- You want exports to design tokens, Tailwind, CSS, Swift, Android.
- You need a public API or AI agent integration (MCP).
When Khroma wins
- You enjoy the personalized "trained on my taste" experience and want to stay in that world.
