Colors
Direction, not random swatches
Say what the brand is for — a mood, an industry, a colour you already have, a logo, a brand you admire — and get three named colour directions. Each is a full system: light and dark, twelve steps per role, semantic colours, checked for contrast, greyscale structure and colour blindness. Previewed on real UI, because the preview is the deliverable.
Three named directions, each a full light + dark system. Deterministic — the same intent always gives the same answer.

Point any MCP client at the shared colors endpoint and your agent gets the same engine as this page — direct_palette, edit_direction, check_palette, check_contrast — read-only, no key. Every direction it proposes comes with a /colors/d/… link: open it, lock what you like, paste the link back, and the agent edits rather than re-rolls.
