Cosmic

Also known as: Winter Dusk, A Stitch in Time, Soul Sister, Filtered Light

A gentle blue with a calm and trustworthy character, Cosmic works beautifully for finance apps and trust-driven interfaces. A yellow counterpart from the complementary harmony gives it the most tension. Accessibility-wise, it needs a dark backdrop — 10.84:1 on black clears AA.

Where Cosmic works

  • Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
  • Interiors: Muted enough to paint all four walls; sample it in both daylight and evening light before committing.
  • Fashion: Works as a base layer or outerwear tone that lets brighter pieces do the talking.
  • Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
  • Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
