Identity
OpenRoomID is public infrastructure. The identity is plain on purpose and borrows its only shape from the identifier itself.
Name
The standard and the project are written OpenRoomID, one word. The identifier it defines is written roomID. The organization is the OpenRoomID Project.
OpenRoomID
Mark
Three bars in the proportion of a roomID’s three segments: eight characters, four, and one. The last bar is registry blue, as the unit suffix is wherever an identifier is shown. It is the only symbol.
Color
Six values. Registry blue appears once in any identifier, on the unit suffix, and otherwise only on links and focus. It is never a background.

Rules
- Sentence case everywhere. No uppercase labels and no tracked-out type.
- An identifier is always set in Plex Mono with the suffix in registry blue.
- Section openings take an ink rule. Rows take a light rule.
- No gradients, shadows, illustrations, or icons other than the mark.
- Copy states facts. The registry says what it knows and never sells.
