Color Scheme Generator
Generate a usable palette from one base color with harmony rules, UI roles, contrast checks and export-ready tokens.
Generate a role-based palette you can actually use in UI, branding or token workflows.

About Color Scheme Generator
Use this color scheme generator when you need more than random swatches. Start from one base color, choose a harmony method, and generate a palette that includes primary, secondary, accent, background, surface and text roles for real interface and brand work.

Why use a structured color scheme generator
A good color tool should not stop at five random hex values. Real design systems need role-based output that can immediately map to buttons, surfaces, backgrounds, text and accents.
This generator is built around usable combinations, not just theoretical color relationships, so you can move from concept to implementation faster.
What the generator creates
You can generate monochromatic, analogous, complementary, split complementary, triadic, tetradic and square schemes from a chosen base color.
The output includes swatches, contrast information, role mapping and copy-ready exports for CSS variables, Tailwind, SCSS and JSON tokens.
Best use cases
It works well for interface design, landing pages, brand systems, component libraries, design QA, prototyping and front-end handoff.
It is especially useful when you want one starting color to drive a complete theme instead of manually building every token yourself.
Frequently asked questions
Does this generate a full UI-ready palette or just swatches?
It generates both. You get a palette plus mapped roles for primary, secondary, accent, background, surface and text so the output is more useful in real projects.
Can I use the output directly in code?
Yes. The generator returns CSS variables, a Tailwind token object, SCSS variables and JSON so you can copy the format that fits your stack.
Does it check accessibility?
Yes. The generated scheme includes contrast readings for key combinations so you can quickly spot whether the palette is moving in a readable direction.
