Plutonium
Also known as: Electric Green , Poison Green , Highlighter Green , Radioactive Green
There is a fresh and natural quality to Plutonium. The vivid, cool green at #35FA00 rewards eco packaging and finance apps. A pink counterpart from the complementary harmony gives it the most tension. For accessible text, use it on black or near-black backgrounds (14.83:1, passes WCAG AA) rather than white.

Where Plutonium 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.
