Cortex

Also known as: Sphinx, Smoky Sunrise, Monkeypod, Tribeca

Quietly bold and energetic, Cortex is a warm-toned red that earns its keep in call-to-action buttons and food branding. A cyan counterpart from the complementary harmony gives it the most tension. Accessibility-wise, it needs a dark backdrop — 7.40:1 on black clears AA.

Where Cortex works

  • Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
  • Interiors: Soft and low-saturation — a candidate for full walls, where vivid colors overwhelm.
  • Fashion: A wardrobe neutral: it anchors outfits and pairs with nearly any accent color.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
  • Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
  • Fashion: Wears best as the statement piece — a top, scarf, or shoes — against neutral basics.
