Bare Greywacke

#2a031f
Notes

Bare Greywacke (#2A031F) is a deep magenta 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 (317°, 87%, 9%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Bare
adjective

Old English bær, naked, exposed — used as a color modifier since the medieval period for hues that read as stripped to their essence. Bare cream, bare gray: low saturation combined with optical directness. Sits at the neutral-bucket alongside plain and spare.

Greywacke
noun

German Grauwacke, gray-stone — the deep-cool-gray graded-bedded turbidite sandstone of the Welsh Borderlands, Lake District, and Hudson Highlands. Greywacke color refers to a Welsh-Borderland Wenlockian-period greywacke outcrop face: a dark cool-gray with the matte finish of poorly sorted feldspar-and-lithic-fragment-rich sandstone on a hand-quarried block-section.
