Decoded design system

E2B's decoded design system: background #FAFAFA, text #000000, accent #3898EC, link #3898EC, primary #0000EE; type scale h1 64px / h2 60px / body 14px; 4px spacing base; 0px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FAFAFA`
surface	`#EBEBEB`
border	`#D4D4D4`
text	`#000000`
text_muted	`#5F5F5F`
primary	`#0000EE`
accent	`#3898EC`
link	`#3898EC`
secondary	`#FF8800`
button_bg	`#000000`
button_text	`#FFFFFF`

Using these colors

Action color #000000 — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #3898EC — one role, not several (the action color).
accent #3898EC — accent for emphasis — keep it rare on the page.
primary #0000EE — a brand color — but the call-to-action uses #000000, not this.
secondary #FF8800 — 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.
