What it is

Radix Colors is a system of 12-step colour scales (30 colours, each with light, dark, alpha and P3 variants) where each step has a defined purpose: backgrounds, borders, solid fills, text. Because every scale follows the same structure, swapping accent colours or themes just works.

Why it’s here

The most useful thing about it is the documentation of what each step is for. Once you know step 9 is the solid colour and step 11 is text, dark mode stops being guesswork. Works with any framework; it's just CSS variables.

Can my agent use this?

Agent excellent agent friendliness

Yes. Docs explain the meaning of each step; ask your agent to use Radix Colors scales and to follow the documented step usage for backgrounds, borders and text.

Excellent: Public docs, public source or an installable package. An agent can read, install and implement this directly.
