Fluorescence

Also known as: Green Lacewing, Emerald Rain, Energise, Fresh Cut Grass

Fluorescence sits on the cool side of the spectrum: a lively green that feels grounded and restorative. Try it in outdoor gear and wellness brands. Its complement lands in purple territory, which makes for striking two-color pairings. Against dark backgrounds it stays legible (11.46:1), but avoid it as text on white.

Where Fluorescence works

  • Web & UI: Best as a button fill, badge, or accent — pair it with white text only at large sizes, and check contrast.
  • 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.
  • Branding: Reads as growth and sustainability — at home in wellness, food, and environmental brands.
  • Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
