Authoritative Tomato

#d21a13
Notes

Authoritative Tomato (#D21A13) 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 (2°, 83%, 45%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Tomato
noun

Solanum lycopersicum — domesticated in Mesoamerica, suspect in sixteenth-century Europe (the Italians called it pomo d'oro, golden apple), and now the most-grown fruit on earth. The color refers to a fully ripe vine-tomato: a saturated red-orange that's warmer than scarlet and brighter than brick. The pigment, lycopene, is the same one that colors watermelon and pink grapefruit.
