Decoded design system

YouTube Music Mobile's decoded design system: background #030303, text #FFFFFF, accent #291A1F, link #291A1F, primary #291A1F; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #291A1F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#030303`
surface	`#121212`
border	`#282828`
text	`#FFFFFF`
text_muted	`#9F9F9F`
primary	`#291A1F`
accent	`#291A1F`
link	`#291A1F`

Using these colors

Action color #291A1F — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #291A1F — one role, not several (the action color).
accent #291A1F — 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.
