Limoncello
#bfff00
Bright lemon-green that softens lime neon edges
About Limoncello
Limoncello reads like a bright, minty green ink mixed with a touch of citrus. It's lighter than the punchy neon signal of Atomic Lime, but it stays more consistently green than Liquid Neon, and it avoids the yellow-lean that makes Neon Yellow feel like a highlighter smear.
For UI, I use it as the one you reach for when you need a clean, optimistic status color without the "notification alarm" edge. It works great in telecom network monitoring, manufacturing yield dashboards, and logistics control rooms where you're layering labels over live maps or feeds. Because it's cool-green with a citrus brightness, it stays legible on dark video and doesn't wander toward yellow-warm.
Quirk: Limoncello can look too light next to charcoal if the rest of the component hierarchy is dim. If you pair it, lean on deeper greens or crisp neutrals so it doesn't feel washed out next to heavier UI colors.
