Central Antracita

#170e19
Notes

Central Antracita (#170E19) is a deep violet with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (289°, 28%, 8%) places it in the muted 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Central
adjective

Latin centrālis, central — adjectival suffix -al. As a color modifier, central implies a neutral-and-central-and-balanced quality where the hue carries the visual register of Mid-Century-Modern and Bauhaus central-and-balanced-and-grounded foundational-design fundamental-element. Sits at the neutral-and-foundational end of the grid, parallel to core and grounded in usage.

Antracita
noun

Spanish antracita, anthracite — adopted into Spanish color terminology for the deep-glossy-black-gray of Asturian-and-Riotinto anthracite-coal seams. Antracita color refers to a freshly cleaved Asturian anthracite-coal block face in raking light: a dark cool-gray with the metallic finish of high-carbon anthracite-coal cleavage. Slightly cooler than English anthracite.
