Becquerel
Also known as: Nuclear Meltdown, Furious Frog, Satin Lime, Vivid Green
Becquerel is a medium, vivid green that reads as calm and balanced. It shines in eco packaging and finance apps. Set it against a purple accent when you want the combination to pop. For accessible text, use it on black or near-black backgrounds (13.31:1, passes WCAG AA) rather than white.

Where Becquerel 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.
