Interference: the Eigna identity
Our brand guidelines, version 1.0: two plates, seven crossings, and the Figure that appears only with your work.

In October 2026 we set down the Eigna identity in our brand guidelines: Interference, version 1.0, 184 pages from the mark to the product screens.
The idea is in the name. Two plates, the base model and your work, are laid in register. Light passes only where both are open, in seven crossings. That is the Figure, and it is the whole idea in one shape: base model plus your work makes your model.
- The mark: the Figure, seven crossings in a vesica, and the wordmark in Onest Light, kerned by hand.
- Type: Onest in Light, Regular and Medium, sentence case everywhere.
- Colour: Graphite, Steel, Slate, Silver, Mist and White, the crossings a cool white. Colour is light, never paint.
- Four lights, each with its word: Ice released, Mineral learning, Sand held, Oxide rolled back.
- Owner figures: one per model, drawn by three numbers from it, on its Model Deed, its device and its app.
- Imagery: one object, one clean light.
Our decks and this site are built on it. Roman explains the thinking in Why our mark is made of light.
