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: #26313F.
  • Keep text in 4 levels: #B3BAC6, #FFFFFF, #F5F5F5, #424B59.
  • Reserve #0261FE for primary actions and key highlights.
  • Reuse the measured spacing steps (8px, 10.4px, 20px).
  • Use 12px corners on most elements; larger surfaces also use 32px and 80px.
  • Use #424B59 for body text; it reaches 2.38:1 on #000000. Keep it for large text or metadata.
  • Introduce new font families beyond Testtiemposheadline and Geist.
  • Use #0261FE for large backgrounds or body text.
  • Make interface transitions slower than 0.4s.

What is the Guestara design system?

The design system on this page is guestara.com’s, as measured on November 3, 2026: Testtiemposheadline type, #0261FE as the main color and 12px corners, written down as a DESIGN.md. It is not Guestara’s own documentation.

What is the Guestara DESIGN.md?

A plain-text file with Guestara’s measured colors, type, spacing, corners and components as tokens, plus short rules, in the DESIGN.md format Google published with Stitch. Your AI coding agent reads it and builds in this style. More about DESIGN.md.

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 Guestara’s official design system?

No. Sitepeel measured it from guestara.com’s public page on November 3, 2026. It is an independent analysis, not made or approved by Guestara.

Can I use Guestara’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 Guestara’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.
