Decoded design system

Dagster's decoded design system: background #FFFFFF, text #111927, accent #4F43DD, link #111927, primary #1F2A37; type scale h1 64px / h2 48px / body 16px; 4px spacing base; 16px base radius. The single interactive/action color is #4F43DD — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#F0F1F2`
border	`#DBDCDE`
text	`#111927`
text_muted	`#6B7079`
primary	`#1F2A37`
accent	`#4F43DD`
link	`#111927`
secondary	`#030615`
button_bg	`#4F43DD`
button_text	`#FFFFFF`

Using these colors

Action color #4F43DD — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #4F43DD — one role, not several (the action color).
accent #4F43DD — 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 #1F2A37 — a brand color — but the call-to-action uses #4F43DD, not this.
link #111927 — inline text links and link-styled controls.
secondary #030615 — 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.
