UI Colors

Turn one brand colour into a full Tailwind-style shade scale.

What it is

UI Colors generates a 50-to-950 shade scale from a single hex colour, in the same format as Tailwind's built-in palettes, with a live preview of the scale on sample UI. Export as Tailwind config, CSS variables, SCSS or SVG.

Why it’s here

The quickest way to get from "our brand is this blue" to a palette your agent can use everywhere. Check the resulting scale for contrast; auto-generated mid steps sometimes need a nudge.

Can my agent use this?

Agent good agent friendliness

Partly. Generate the scale, copy the export, and give it to your agent as your palette.

Good: Publicly accessible and useful to reference, but the agent will need to interpret it rather than install it.
