Subtle Ebony

#506456
Notes

Subtle Ebony (#506456) is a true green 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 (138°, 11%, 35%) 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

Subtle
adjective

Latin subtilis, finely woven — used as a color modifier since the medieval period for hues that read as understated and easily missed. Subtle olive, subtle taupe: low saturation combined with optical quietness. Sits at the hushed-bucket alongside muted and modest.

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.
