Tana thinks in serif: Source Serif 4 at 72px/500 in warm ink #0C0805 on paper #FBFBFB ('Do work in the meeting'), Inter for the 17-22px working text and 14px-radius ghost buttons. Node-graph UI and AI-agenda panels sit inside generous editorial whitespace — a knowledge tool typeset like the long-form thinking it wants to hold.

Tokens

Tana's decoded design system: background #FBFBFB, text #0C0805, accent #0C0805, link #0000EE, primary #ECE4D4; type scale h1 72px / h2 48px / body 18px; 4px spacing base; 12px base radius. The single interactive/action color is #0C0805 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FBFBFB`
surface	`#ECECEC`
border	`#D7D6D6`
text	`#0C0805`
text_muted	`#666462`

accent	`#0C0805`
link	`#0000EE`
secondary	`#D88A82`
button_bg	`#0C0805`
button_text	`#FFFFFF`

Using these colors

Action color #0C0805 — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #0C0805 — one role, not several (the action color).
accent #0C0805 — 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 #ECE4D4 — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #0C0805).
link #0000EE — inline text links and link-styled controls.
secondary #D88A82 — 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.
