Smoky Espresso

#40290b
Notes

Smoky Espresso (#40290B) is a deep orange 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 (34°, 71%, 15%) 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

Smoky
adjective

An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.

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.
