Raging Thunderstorm

Rain hits a metal awning and the surface goes that slate-blue damp, heavy and intent. Raging Thunderstorm sits in that same lane, but it's less night-muted than Nocturnal Expedition and less wetsuit-smooth than Plunge. Compared to Juggernaut's dense glass-ink feel, this one reads more stormy and dimensional, with a deeper teal-lean that keeps it from becoming purely slate.

I use it for the one you reach for when a UI needs authority without shrinking into near-black, especially in dashboards and data-heavy operations portals where panel borders, chart rails, and status tiles must look "set" rather than shadowed. In healthcare software, it's great for secondary CTAs and table highlights that still need to hold steady beside bright labels.

Quirk: pair it with grays that aren't too cool or it can start to feel stricter than you want. Give it some breathing room with softer neutrals and it plays nicer.
