Smoldering Tomato

#a42d2b
Notes

Smoldering Tomato (#A42D2B) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (1°, 58%, 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

Smoldering
adjective

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

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.
