Sour Green

Brighter, cleaner chartreuse for subtle success states
About Sour Green
Sour Green looks like a lime that's been knocked back with a touch of yellow acid, then left slightly dusty instead of crisp. It's light enough to read fast, but it doesn't carry the alert cleanliness of the greener neighbors. Compared to Lush Green's confident, leaf-clean fill, this one feels more tangy and a bit less "fresh success."
I use Sour Green for dashboards and finance apps when the status needs to feel "processed but still under scrutiny." Think risk review queues, fraud or compliance triage, inventory exception chips, and production steps that are green-lit with conditions. It also works in logistics UIs for "in transit, check at next node" labels, especially on cool grays where it won't blur into nearby leaf tones. Compared with Poisonous Pesto, it's less ink-settled and more sun-diluted, so it flags attention without looking as harsh.
Pair it with charcoal text and cool off-whites. If your background runs warm, it can start to feel overly sharp and restless, so keep the surrounding whites on the cooler side.
