Indomitable Flamingo

#b53d1b
Notes

Indomitable Flamingo (#B53D1B) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (13°, 74%, 41%) 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

Indomitable
adjective

Latin indomitābilis, unconquerable — derived from domāre (to tame). As a color modifier, indomitable implies a saturated-and-unconquerable-and-fierce quality where the hue resists any attempt to subdue or modulate its presence. Sits at the bold-and-resilient end of the grid, parallel to unyielding and adamant.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
