Fluorescence

Fluorescence is the green I notice when a UI looks "lit from within." It has that high-energy, almost neon-sheen brightness, but it stays clean and controlled, not minty like Gossip and not jewel-dense like Enchanted Emerald.

Compared to Feijoa's softer garden-fruit feel, this one is lighter and more electric in its undertone. I reach for it when you need a highlight that still reads unmistakably green, like delivery and logistics progress states, warehouse scan confirmations, and sustainability widgets where you want attention without sliding into chart-green urgency. It also works well in product thumbnails for consumer goods, where the background needs a quick punch of green that stays legible next to neutrals.

Quirk: because it's so bright, it can feel intense against very cool grays. If you use it as a background wash, pair it with a calmer green border or a slightly warmer off-white so the glow doesn't take over.
