Loud Lime

I keep seeing Loud Lime pop up in prototypes as a bright, almost fluorescent highlight that feels more "lime-saturated" than "signal-clean." Compared to Acid Green, it's not yellow-warm and pulsingly electric. Compared to Lime, it holds its intensity harder and reads a bit more aggressively, with a cooler, greener undertone that doesn't soften into that friendly traffic-sign glow.

On screens, it's the one you reach for when you want alerts to land fast without drifting toward chartreuse. I've used it in trading dashboards for "active" price movement markers, in live event timelines for newly received updates, and on mapping interfaces to lock attention on current vehicle or route status. The catch: it stays crisp, but it can look overly loud next to midtones or warm grays.

Pair it with deep charcoal or true black for control, and give it breathing room. If you spread it across a whole UI, it starts to feel like noise instead of direction.
