Dominant Tomato

#a21e0c
Notes

Dominant Tomato (#A21E0C) is a deep red 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 (7°, 86%, 34%) places it in the highly saturated band at a dark 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

Dominant
adjective

Latin dominārī, to rule — present-participle of dominate. As a color modifier, dominant implies a saturated-and-leading quality where the hue claims visual precedence over neighboring colors in the surrounding palette. Sits at the bold-and-imperative end of the grid, parallel to commanding and authoritative.

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.
