Ominous Espresso

#36240b
Notes

Ominous Espresso (#36240B) is a deep amber 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 (35°, 66%, 13%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Ominous
adjective

Latin ōminōsus, full of foreboding — derived from omen. As a color modifier, ominous implies a deep-and-threatening atmospheric-foreboding quality, the dark cool-gray of Goyaesque storm-laden sky. Sits at the deep-and-threatening end of the grid, parallel to foreboding and menacing in tone.

Espresso
noun

The concentrated coffee shot extracted under pressure — Italian café standard since the late nineteenth century, with the dark roast that distinguishes it from filter coffee. The color refers to a fresh-pulled espresso in a white cup: a deep, slightly red-shifted near-black with the slight crema of suspended oils on the surface. Warmer than coal, glossier than mascara, with the café weight of a beverage measured in twenty-five-milliliter shots.
