Vivid Green
#2fef10
High-saturation neon green for sharp, cool-focused highlights
About Vivid Green
I keep thinking of Vivid Green as the green you get when lime brightness stays disciplined and stops trying to look like a marker. Compared to Satin Lime, it feels less leaf-spring and more crisply defined, with a tighter undertone that doesn't tip yellow. Next to Nuclear Meltdown, it's bright too, but it reads cleaner and less "high-alert" in the moment.
This is the shade I pull for production line callouts, warehouse batch tags, and field-tech checklists where the green needs to look decisive in harsh light. In UI terms it's great for primary confirmation actions, "success" states, and progress steps when you don't want the cool stress of that neon, warning-adjacent vibe. It also works well for logistics maps and esports-style overlays that need the one you reach for when accents start repeating.
Quirk: because the saturation is high, it can feel loud against very pale skins or pastel layouts. Pair it with deep forest greens or near-black type to keep it from stealing the frame.
