Why it works and how to use it

It works because the lightness range is wide (29% to 97%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.

  • Background: Snow (#FBFAF6) is the lightest color, so it belongs on large surfaces.
  • Text: Spruce (#355D4B) on #FBFAF6 gives 7.13:1, passing WCAG AAA.
  • Primary: Fern (#427E62) is the most saturated mid-tone; use it for buttons and links (4.58:1 against the background, fine for UI elements).
  • Accent: Fog (#CECEBB) for highlights, badges and hover states.
