Sterile Flamingo

#a1481f
Notes

Sterile Flamingo (#A1481F) is a true orange with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (19°, 68%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Flamingo
noun

The genus Phoenicopterus — wading birds whose pink-orange plumage comes from carotenoid pigments in the brine shrimp and algae they eat. The color refers to a Caribbean flamingo's neck plumage: a soft, slightly cool pink-orange with the matte finish of dietary-pigmented feathers. Cooler than coral, warmer than salmon.
