Thunderbird

Thunderbird looks like a burnished burnt-umber orange that's been pulled away from tomato and cherry. It's darker than the usual bright orange, but it doesn't drift all the way into chocolate brown. Compared to Ripasso, it feels less cleanly red and more brown-red under the surface. Compared to Sizzling Bacon, it's tighter and less ember-splashed, more like a single pressed tone. Versus Ketchup, it's a touch more muted and less "rusty-spiced," so the orange stays present without turning flat.

I reach for it when the UI needs urgency with a steadier, grounded mood: dashboards and finance apps for risk and status labels that shouldn't shout. It's also great in logistics portals for override states and in ecommerce admin screens for editorial callouts where you want attention but not that glossy "hot now" feel.

Quirk: on very light UIs it can read a bit heavier and browner than you expect, so pair it with warm neutrals or darker grays instead of pale creams.
