Decoded design system

Character.AI Mobile's decoded design system: background #131313, text #8FB8C3, accent #195EFF, link #195EFF, primary #195EFF; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #195EFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Using these colors

Action color #195EFF — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #195EFF — one role, not several (the action color).
accent #195EFF — 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.
