Decoded design system

Outlook Mobile's decoded design system: background #FFFFFF, text #000000, accent #0063B7, link #0063B7, primary #0063B7; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #0063B7 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#0063B7`
accent	`#0063B7`
link	`#0063B7`
button_bg	`#0063B7`
button_text	`#FFFFFF`

Using these colors

Action color #0063B7 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #0063B7 — one role, not several (the action color).
accent #0063B7 — 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.
