Adequately Bronzite

#172421
Notes

Adequately Bronzite (#172421) is a deep 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 (166°, 22%, 12%) places it in the muted band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Adequately
adjective

Latin adaequātus, made equal — adverbial-and-adjectival suffix -ly. As a color modifier, adequately implies a neutral-and-sufficient-and-fitting quality where the hue carries the visual register of sufficiently-fitting-and-adequately-coordinated color-decision matched to its functional requirement. Sits at the neutral-and-traditional end of the grid, parallel to sufficiently and appropriately in usage.

Bronzite
noun

(Mg,Fe)SiO₃ iron-bearing pyroxene — a deep-bronze-gray mineral mined principally at Kraubath in Austria and Webster in North Carolina, the namesake of the Bronze Age. Bronzite color refers to a freshly cleaved Kraubath bronzite schiller-cleavage face: a dark cool-gray with the metallic finish of orthorhombic-system iron-magnesium pyroxene with chatoyant-iron schiller.
