Rust

Also known as: Donkey Kong, Burnt Sienna, Muddy, Rusted Lock

Rust brings a earthy and grounded feel to any palette. This rich brown is a natural fit for autumn design and coffee and food branding. A cyan counterpart from the complementary harmony gives it the most tension. It's dark enough to use for text on white backgrounds (6.33:1, passes WCAG AA).

Where Rust works

  • Web & UI: Use it directly for text on light surfaces; it clears AA contrast without adjustment.
  • Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
  • Fashion: Works as a base layer or outerwear tone that lets brighter pieces do the talking.
  • Branding: As a brand anchor it reads established and tactile; pair with a single vivid accent for energy.
  • Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
