Decoded design system

Otter's decoded design system: background #FFFFFF, text #000000, accent #1D25E2, link #1D25E2, primary #144FFF; type scale h1 60px / h2 56px / body 12px; 4px spacing base; 16px base radius. The single interactive/action color is #1D25E2 — 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	`#144FFF`
accent	`#1D25E2`
link	`#1D25E2`
secondary	`#5A5DA3`
button_bg	`#1D25E2`
button_text	`#FFFFFF`

Using these colors

Action color #1D25E2 — the single interactive color; only on things you click or must notice, never large fills.
accent, link, button_bg are all #1D25E2 — one role, not several (the action color).
accent #1D25E2 — 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.
primary #144FFF — a brand color — but the call-to-action uses #1D25E2, not this.
secondary #5A5DA3 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
