Exa — design system & UI screens
Light landing scattered with floating sky-and-cloud image tiles around a centered headline and an API search-results table mockup; logo wall (Vercel, Cursor, Databricks, Groq, Gamma).
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/exa.
Decoded design system
Exa's decoded design system: background #FFFFFF, text #000000, accent #000000, link #374151, primary #1F40ED; type scale h1 63.2px / h2 48px / body 18.4px; 4px spacing base; 4px 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.

Using these colors
- Action color
#000000— the single interactive color; only on things you click or must notice, never large fills. accent,button_bgare all#000000— one role, not several (the action color).- accent
#000000— 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
#1F40ED— a brand color — but the call-to-action uses #000000, not this. - link
#374151— inline text links and link-styled controls. - secondary
#EEF8FF— 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.
