Sourcegraph — design system & UI screens

Dev Tools · 1 screen · 11 sections · https://sourcegraph.com/

Dark hero over a code-search product UI and a 200+ enterprise logo wall.

This is a static, crawlable rendering for search & AI engines. The interactive version — filters, live decode console, copy & export — is at https://mozaika.design/website/sourcegraph.

Decoded design system

Sourcegraph's decoded design system: background #0E0D0D, text #ECECEE, accent #F34E3F, link #080E2C, primary #9E9EFF; type scale h1 80px / h2 34px / body 22px; 4px spacing base; 8px base radius. The single interactive/action color is #F34E3F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#0E0D0D`
surface	`#1B1A1A`
border	`#2F2E2E`
text	`#ECECEE`
text_muted	`#979798`
primary	`#9E9EFF`
accent	`#F34E3F`
link	`#080E2C`
secondary	`#410604`
button_bg	`#F34E3F`
button_text	`#FFFFFF`

Using these colors

Action color #F34E3F — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #F34E3F — one role, not several (the action color).
accent #F34E3F — 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 #9E9EFF — a brand color — but the call-to-action uses #F34E3F, not this.
link #080E2C — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #410604 — 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.
