02 · Meaning · Signal Language
Four signals. Each one says exactly one thing.
02 / 22
Signals describe state — what something is doing. Kinds (next section) describe identity — what something is. They share a color range but not a surface: signals live on badges, rails, and tints; kinds live on glyphs, thumbnails, and nav dots. If nothing in the composition is failed, running, pending, or complete, nothing in the composition is red, amber, blue, or green.
| Signal | Meaning | Use for | Never for |
|---|---|---|---|
| Red | Destructive · Failed · Active attention | Delete, failed generation, deploy button, attention badges | Decorative accents, brand flourish, "primary" CTAs |
| Blue | In-progress · Linked · Agent | Generating states, linked integrations, agent-owned UI | Generic links (use ink-2 underlines instead) |
| Amber | Waiting · Pending · Warning | Queued jobs, pending review, soft warnings | "Interesting" or "highlighted" — amber is a state, not a flag |
| Green | Published · Healthy · Complete | Success confirmations, published figments, healthy systems | Generic positive emphasis — success isn't decoration |
