Somber Tomato

#5a1227
Notes

Somber Tomato (#5A1227) 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 (343°, 67%, 21%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Somber
adjective

From the French sombre, dark, gloomy — itself from the Latin sub umbra, under shadow. Used as a color word since the eighteenth century to imply restrained darkness — the deep grays and blue-blacks of mourning dress and Victorian parlor decoration. Sits in the deep-and-quiet end of the grid, closer to brooding than to charred.

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.
