Country Pyrolusite

#15042a
Notes

Country Pyrolusite (#15042A) is a deep indigo 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 (267°, 83%, 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Pyrolusite
noun

β-MnO₂ manganese-dioxide mineral — the principal ore of manganese metal and the cave-art black-pigment of Lascaux and Altamira (40,000–15,000 BP). Pyrolusite color refers to a freshly cleaved Ilfeld pyrolusite dendritic-fan-cluster face: a saturated, slightly cool deep black with the matte finish of tetragonal-system manganese-dioxide. The Greek genus name pyro-lousis refers to its use in glass-making.
