Realm of the Underworld

I keep running into Realm of the Underworld on old-school signage and it always reads like inked foliage, not garden green. It's deeper and more muted than British Racing Green, and it doesn't have that cool-water density of Deep Pond. Compared to Myrtle, this one feels less gray-dyed and more shadow-forward, with a slightly warmer undertone that pulls it away from "clean" and toward "buried."

In UI, it's the shade I grab when a status panel needs weight without going brownish or muddy, especially for industrial control dashboards, asset tracking screens in utilities, and timeline headers in field ops apps. On packaging and labeling, it holds up on matte stocks where brighter greens can look sprayed-on. Use it as a primary on dark surfaces, or as a bold accent on white layouts where you want emphasis that feels controlled, not loud.

Pair it with crisp off-whites or cool charcoals. If you stack it next to very warm neutrals, the undertone starts to wander.
