Do’s and don’ts

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

  • Use #1D1D21 for the page and lift surfaces in small steps: #303136.
  • Keep text in 2 levels: #D2D2D3, #FFFFFF.
  • Use #CBB88E as the brand accent: header, logo and key highlights.
  • Set headlines in agileSans with tight tracking (-0.02em).
  • Reuse the measured spacing steps (8px, 12px, 24px).
  • Make buttons and chips fully rounded (9999px); most other elements use 2px corners.
  • Add drop shadows for depth; use tonal surfaces.
  • Introduce new font families beyond agileSans.
  • Use #CBB88E for large backgrounds or body text.
  • Make interface transitions slower than 0.3s.

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 1Password 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, agileSans 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 1Password’s official design system?

No. Sitepeel measured it from 1password.com’s public page on October 21, 2026. It is an independent analysis, not made or approved by 1Password.

Can I use 1Password’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 1Password’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.
