Color

Palette

Carbon is the ground and Fog is the type; together they are nearly the whole brand. Graphite and Ash are the greys between them for panels, borders and secondary text. Signal, running orange into magenta, is light on the crystal: used once per screen, where attention belongs. Take values from the tiles, never from a screenshot.

Proportion

Carbon carries almost everything. Fog is every word. Graphite and Ash build the interface quietly. Signal is a line, a glow or a single word, never a background.

Contrast

Pairings that stay readable on a dark screen in a bright room. Fog on Carbon carries all text; Ash on Carbon is for secondary text at reading size and above. Signal on Carbon works for headlines and accents, never for body copy. Check anything below 14 pixels before it ships.

Color modes

Halide lives on screens, so RGB and hex are the source of truth. For print, Carbon prints as rich black and the Signal gradient needs a proof: match the two Pantones at its ends and let the press blend them.
