How to use #7b71fd

Derived from its contrast, chroma and lightness — not from taste.

  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care

  • White text placed on it
  • Pairing with a same-lightness hue — edges vibrate
