03. The
Nebula.

Chapter 03·Identity mark
Six beams converging on a golden core, inside a breathing atmosphere. Six, not five, not seven — it's never a star. It's a place you meet.
The primary mark

Six beams.
One golden core.

Each beam is a different pale nebula color. They fade from bright at the origin to transparent at the core — light traveling toward something, not radiating away.

The gold core has three layers: a soft blur, a warm radial gradient, and a white highlight. It is the only true warm element. Everything else is cool.

Construction.

The mark is built on a 120-unit grid with a central origin. The six beam endpoints sit on a 50-unit circle at specific angles — roughly 10, 12, 2, 9, 4, 3 on a clock face. The asymmetry is intentional.

Variants.

Eight approved forms. Start with the full mark on obsidian. Drop to mono only when the surface demands it — print, embossing, single-color partners. Never recolor the beams.

Clear space.

The mark breathes. Give it room equal to the core diameter on every side — about 1/6 of the mark's total size. Never let type or image cross the invisible boundary.

Sizing.

Minimum 16px in any digital use. Below that the core collapses into a single pixel and the beams ghost out. For favicons, we use a simplified 3-beam version.

Favicon & social.

Tiny contexts. A browser tab, a Twitter avatar, a Slack channel icon. Simplified so the core reads at 16px and the roundel works on any background.

Never do.

Six ways the mark breaks. These aren't style preferences — each one erases something the symbol is supposed to mean.
