Do’s and don’ts

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

  • Use #000000 for the page and lift surfaces in small steps: #1A1A1A, #333333.
  • Keep text in 4 levels: #FFFFFF, #E5E5E5, #B2B2B2, #696969.
  • Let contrast carry emphasis; primary actions use #E2DFE9 on #000000.
  • Reuse the measured spacing steps (6px, 15px, 25px).
  • Use 3px corners on most elements.
  • Use #696969 for body text; it reaches 3.8:1 on #000000. Keep it for large text or metadata.
  • Introduce new font families beyond areal.
  • Add saturated accent colors; the measured palette is almost entirely neutral.

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 Are.na 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, areal 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 Are.na’s official design system?

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

Can I use Are.na’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 Are.na’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.
