Mid-light, saturated spring green with rich, minty edge
About Poison Ivy
I keep thinking of Poison Ivy as the sharp green that shows up on glossy, fresh leaves right after a drizzle. It's deeper and more saturated than the garden-style greens around it, but it doesn't slide toward the leafy-yellow that would make it feel cheap. The temperature reads slightly cooler than the warmer yard greens, and the undertone stays clean and botanical rather than mossy or smoky.
In production UIs, I treat it like a "go" signal that still feels controlled: dashboards and finance apps need quick positive state cues, and Poison Ivy holds that line without looking neon next to cream cards. I use it for KPI deltas, verified chips, and logistics progress markers where the green must stay legible against neutral panels that lean warm. Compared with Hanging Gardens of Babylon, this one feels more dense and less airy. Versus Fennel Fiasco, it's less herb-bright under studio light. And beside Matt Green, it carries more punch and less matte calm.
One quirk: on very warm off-white, it can feel a touch sharper than you expect, so I'll soften the background or give it a little extra padding.
