Entirely free — the site states there is no account, no paywall and no paid tier, and the public REST API and MCP server need no key, under a fair-use policy.
Use tool ↗About colorfor.ai
colorfor.ai is a browser-based set of colour tools that turns a text description, a logo or a few brand colours into a palette and a full design-token system. It checks contrast against WCAG, builds themes across about 40 semantic UI roles, simulates colour blindness, and exports CSS variables, Tailwind ramps, shadcn variables, SCSS or JSON. Everything is free with no account, paywall or paid tier, and the same engine is exposed as a free keyless REST API and an MCP server for code and AI agents. The about page says the site is built and operated with Biela, an app builder, and gives a Biela contact address; no company entity or country is named.

Pros & cons of colorfor.ai
colorfor.ai covers the full path from a text description to production-ready color tokens - palette, contrast-checked theme, and export formats - for free, with none of the usual account or paywall friction. Without any company identity behind it, it's worth treating output as a starting point rather than a fully supported product.
Pros
- No account or payment required for any feature
- Exports directly to CSS, Tailwind, shadcn, and JSON formats
- Includes WCAG contrast checking, not just color aesthetics
- Free keyless REST API and MCP server expose the same engine to code and agents
Cons
- No company entity or country named — only a note that it is built and operated with Biela
- No account means no saved history across sessions, based on the site's own framing
- Free tools like this with no visible business model can disappear without notice
Best for
- Designers and developers who want WCAG-checked color systems fast
- Anyone wanting Tailwind or shadcn-ready color tokens without manual conversion
- Solo developers who don't want to create an account for a one-off palette
Not for
- Teams wanting a supported, company-backed tool with account history
- Anyone needing team collaboration or saved-project features
