Halogen design system

A dark-first design system with light and dark color schemes. Shaped for dense dashboards, creative tools, and AI product interfaces.

How to use it

Install the system, run the prompt, ship the result. No styling debt, no inconsistencies, no late polish round.

Step 1

Drop the kit into your project. One npx command lands the files in place. Or copy them in by hand.

Step 2

Open the included prompts in Claude Cowork. Paste them in and describe your product idea.

Step 3

A working, on-system interface comes back. Tokens, components, motion, and copy already aligned.
