Why it works and how to use it

It works because the lightness range is wide (0% to 93%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.

  • Background: Frost (#EDEDED) is the lightest color, so it belongs on large surfaces.
  • Text: Black (#000000) on #EDEDED gives 17.94:1, passing WCAG AAA.
  • Primary: Onyx (#3A3A3A) is the most saturated mid-tone; use it for buttons and links (9.72:1 against the background, fine for UI elements).
  • Accent: Gray (#7A7A7A) for highlights, badges and hover states.
