Decoded design system

YouTube Mobile's decoded design system: background #000000, text #FFFFFF, accent #E9528F, link #E9528F, primary #E9528F; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #E9528F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#000000`
surface	`#0F0F0F`
border	`#262626`
text	`#FFFFFF`
text_muted	`#9E9E9E`
primary	`#E9528F`
accent	`#E9528F`
link	`#E9528F`

Using these colors

Action color #E9528F — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #E9528F — one role, not several (the action color).
accent #E9528F — 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.
