Tokens

Fey's decoded design system: background #000000, text #868F97, accent #479FFA, link #479FFA, primary #868F97; type scale h1 54px / h2 26px / body 14px; 12px spacing base; 14px 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

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 #479FFA — one role, not several (the action color).
• accent #479FFA — accent for emphasis — keep it rare on the page.
• primary #868F97 — ≈ the text color — a foreground/text color, not an action color (action = #000000).
• secondary #D88036 — 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.
