Do’s and don’ts

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

  • Use #FAFAFA for the page.
  • Keep text in 3 levels: #414141, #000000, #737373.
  • Use #FBCA00 as the brand accent: header, logo and key highlights.
  • Keep spacing on the 4px grid.
  • Add drop shadows for depth; use borders and contrast.
  • Introduce new font families beyond ui-monospace.
  • Use #FBCA00 for large backgrounds or body text.
  • Make interface transitions slower than 0.15s.

Can I use PlanetScale’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 PlanetScale’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.
