#66dd00 - Radioactive Lilypad color
Vivid lime-green with an electric, neon edge—zesty and highly saturated. It reads as bright chartreuse, midway between yellow and green, evoking fresh spring foliage, citrus, and energetic youthfulness. Luminous and attention-grabbing, it works well for accents, call-to-action buttons, and eco or tech themes but can be overwhelming on large surfaces or against light backgrounds. Best paired with deep neutrals, charcoal, or muted blues for contrast and legibility.
