Fluorescence
Also known as: Green Lacewing , Emerald Rain , Energise , Fresh Cut Grass
A lively green with a grounded and restorative character, Fluorescence works well for 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, and empty-state illustrations, but not text.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
