Rustic Ebony

#5b6f64
Notes

Rustic Ebony (#5B6F64) is a true teal 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 (147°, 10%, 40%) places it in the muted 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Rustic
adjective

Latin rusticus, of the countryside — used as a color modifier since the seventeenth century for hues that read as rural and unrefined. Rustic brown, rustic green: moderate-to-low saturation combined with the optical irregularity of natural pigments. Sits at the hushed-bucket alongside worn and weathered.

Ebony
noun

The genus Diospyros — particularly D. ebenum of Sri Lanka and D. crassiflora of West Africa — whose dense black heartwood has been carved for ornament since the Egyptian Old Kingdom. The color refers to polished African blackwood: a deep, slightly warm matte black with the satin finish of close-grained hardwood. Warmer than obsidian, drier than pitch, with the carving weight of a wood that sinks in water and sharpens its own tools.
