Decoded design system

Nubank Mobile's decoded design system: background #FFFFFF, text #191919, accent #17C242, link #17C242, primary #17C242; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #17C242 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F1F1F1`
border	`#DCDCDC`
text	`#191919`
text_muted	`#707070`
primary	`#17C242`
accent	`#17C242`
link	`#17C242`
button_bg	`#17C242`

Using these colors

Action color #17C242 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #17C242 — one role, not several (the action color).
accent #17C242 — 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.
