Radioactive
Also known as: Lasting Lime, Bright Lime, Lethal Lime, Acid Green
As a medium take on green, Radioactive carries calm and balanced energy that suits finance apps and outdoor gear. Because it leans warm, balancing it with a purple keeps a palette from feeling one-note. For accessible text, use it on black or near-black backgrounds (16.24:1, passes WCAG AA) rather than white.

Where Radioactive works
- Web & UI: Reads as an interactive accent: fills, hovers, focus rings. Keep body text in a darker neutral.
- Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
- Fashion: One garment in this color carries an outfit; two starts to compete.
- Branding: A brand green signals freshness; deepen it for finance, brighten it for eco-consumer products.
- Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
- Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
