Unassuming Manganite

#120427
Notes

Unassuming Manganite (#120427) 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 (264°, 81%, 8%) 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.

Etymology

Unassuming
adjective

Latin assūmere, to take up — negative-prefix un- plus present-participle of assume. As a color modifier, unassuming implies a neutral-and-modest-and-not-claiming-attention quality where the hue carries the visual register of Mid-Century-Modern modest-and-quiet-and-unobtrusive interior-decoration surface. Sits at the neutral-and-stripped-down end of the grid, parallel to simple and modest in usage.

Manganite
noun

γ-MnO(OH) manganese hydroxide-oxide mineral — a deep-black orthorhombic mineral mined principally at Ilfeld in Germany and Negaunee in Michigan. Manganite color refers to a freshly cleaved Ilfeld manganite prismatic-cluster face: a saturated, slightly cool deep black with the metallic finish of orthorhombic manganese-hydroxide-oxide. One of the principal ores of manganese metal, also a steel-alloy and dry-cell-battery component.
