Sterile Tabasco

#973e4a
Notes

Sterile Tabasco (#973E4A) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (352°, 42%, 42%) 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 teal. 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.

Tabasco
noun

The Mexican state — and the brand of pepper sauce produced there since 1868 from Capsicum frutescens. Tabasco as a color refers to the bright red-orange of the famous sauce: a saturated, slightly orange red with the slight viscosity of vinegar-and-pepper extract. Brighter than rust, warmer than tomato.

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.
