Do’s and don’ts

Rules written from the measurements, so a coding agent stays on style.

  • Use #FFFFFF for the page and lift surfaces in small steps: #DCFDFF, #F4F7F7, #F5F5F5, #E5E5E5.
  • Keep text in 4 levels: #3A3B3C, #151515, #646567, #929394.
  • Let contrast carry emphasis; primary actions use #000000 on #FFFFFF.
  • Reuse the measured spacing steps (8px, 10px, 24px).
  • Use 8px corners on most elements; larger surfaces also use 18px, 10px and 14px.
  • Use #929394 for body text; it reaches 3.1:1 on #FFFFFF. Keep it for large text or metadata.
  • Introduce new font families beyond Sora and Inter.
  • Add saturated accent colors; the measured palette is almost entirely neutral.
  • Make interface transitions slower than 0.5s.

What you can build with it

Landing pages, pricing tables, dashboards: your AI coding agent builds them in this style, with these colors, fonts, spacing and buttons instead of its defaults.

Download DESIGN.md, put it in your project’s root folder, then ask your agent for a page.

FAQ

Questions

What can I build with the Prisma DESIGN.md?

Any page or component in this style: a landing page, pricing table, dashboard or sign-up form. Your AI coding agent uses the measured colors, Sora type, spacing, corners and buttons instead of its own defaults.

How do I use it with Claude Code or Cursor?

Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.

Is this Prisma’s official design system?

No. Sitepeel measured it from prisma.io’s public page on October 21, 2026. It is an independent analysis, not made or approved by Prisma.

Can I use Prisma’s style in my own product?

Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Prisma’s logo, name, pictures or text.

How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.
