Do’s and don’ts

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

  • Use #000000 for the page.
  • Keep text in 3 levels: #FFFFFF, #EFEFEF, #999999.
  • Let contrast carry emphasis; primary actions use #FFFFFF on #000000.
  • Keep spacing on the 4px grid.
  • Use 6px corners on most elements.
  • Add drop shadows for depth; use borders and contrast.
  • Introduce new font families beyond Apple Garamond Regular, Inter, sans-serif, Inter-Medium and courier new.
  • Add saturated accent colors; the measured palette is almost entirely neutral.

FAQ

Questions

What can I build with the Thibaut 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, Apple Garamond Regular 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 Thibaut’s official design system?

No. Sitepeel measured it from thibaut.cool’s public page on October 23, 2026. It is an independent analysis, not made or approved by Thibaut.

Can I use Thibaut’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 Thibaut’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.
