Tokens

Bun's decoded design system: background #14151A, text #ECECEE, accent #9CA3AF, link #9CA3AF, primary #F472B6; type scale h1 53.3333px / h2 24px / body 16px; 4px spacing base; 5px base radius. The single interactive/action color is #14151A — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#14151A`
surface	`#202126`
border	`#343539`
text	`#ECECEE`
text_muted	`#999A9D`
primary	`#F472B6`
accent	`#9CA3AF`
link	`#9CA3AF`
secondary	`#3B3F4B`
button_bg	`#14151A`
button_text	`#D1D5DB`

Using these colors

Action color #14151A — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #9CA3AF — one role, not several (the action color).
accent #9CA3AF — accent for emphasis — keep it rare on the page.
primary #F472B6 — a brand color — but the call-to-action uses #14151A, not this.
secondary #3B3F4B — 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.
