Effulgent Cape Malachite
Effulgent Cape Malachite (#14B260) is a true teal with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (149°, 80%, 39%) places it in the highly saturated band at a mid 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin effulgēns, shining-out — present-participle of effulgere, sharing root with fulgor (lightning). As a color modifier, effulgent implies a saturated-and-radiating-light-out quality, the bright color of Renaissance-Madonna halo-and-aureole gold-leaf-and-pigment emission. Sits at the bright-and-saturated end of the grid, parallel to resplendent and radiant in usage.
Latin cappa, hooded-cloak. As a color modifier, cape implies a hooded-cloak-and-shoulder-cape quality, the visual register of Spanish-capa-and-Italian-cappa-magna hand-hooded-cloak-and-shoulder-cape Spanish-capa-and-Italian-cappa-magna-and-Portuguese-capa cape-and-hooded-cloak-and-shoulder-cape surfaces under Spanish-capa-and-Italian-cappa-magna-and-Portuguese-capa Iberian-and-Italian-Renaissance Iberian-cape-light. Sits at the modifier-and-textile end of the grid, parallel to cloak and cope in usage.
A copper carbonate mineral — Cu₂CO₃(OH)₂ — that crystallizes as concentric green bands in oxidized copper deposits. Mined for ornamental stone since ancient Egypt, ground into pigment for medieval European painting, polished into the malachite columns of the Russian Hermitage. The color refers to a polished cabochon: a saturated, slightly muted green with the high shine of stone and the visible banding of growth rings.
