Bullfrog

Bullfrog sits in that narrow band where green stops feeling like it's trying to prove something. It's got enough yellow underneath to feel alive, but it doesn't push forward the way Buckingham Gardens does. The saturation is there, it won't flatten or shift toward gray depending on what's next to it, but the overall temperature lands cooler and more restrained than Backyard, which means it settles instead of announces.

This is the one I reach for on health apps, environmental dashboards, and productivity tools where you need green that feels trustworthy without being corporate. It reads cleanly as a background color without fatiguing at scale, pairs naturally with warm and cool neutrals alike, and actually maintains its character across different screen temperatures. Unlike Artichoke's studied mutedness, Bullfrog has real presence without demanding attention. It's got more structural weight than the brighter greens but refuses to compete with content.

Pair it with charcoal type, warm grays, or soft white and it just stays put. The catch: test it at actual size first. It's the kind of color that reads differently in a component versus spread across a full section, but once you see it at scale, you'll know immediately if it's the right fit.
