Why it works and how to use it

It works because the lightness range is wide (0% to 100%), which gives clear hierarchy between background, content and accents. Try it for websites, presentations and branding.

  • Background: White (#FFFFFF) is the lightest color, so it belongs on large surfaces.
  • Text: Black (#000000) on #FFFFFF gives 21:1, passing WCAG AAA.
  • Primary: Storm (#5C5C5C) is the most saturated mid-tone; use it for buttons and links (6.69:1 against the background, fine for UI elements).
  • Accent: Silver (#BDBDBD) for highlights, badges and hover states.

3 of 6 color pairs pass WCAG AA (4.5:1); the strongest is Black on White at 21:1.
