Tokens

Doom 64 UI's decoded design system: background #1A1A1A, text #E0E0E0, accent #E53935, link #E53935, primary #E53935; type scale h1 36px / h2 24px / body 14px; 4px spacing base; 0px base radius. The single interactive/action color is #E53935 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #E53935 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #E53935 — one role, not several (the action color).
• accent #E53935 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
