Decorously Tenebrae
Decorously Tenebrae (#1E0121) is a deep violet 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 (294°, 94%, 7%) 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
Latin decōrōsus, seemly / proper — adverbial-and-adjectival suffix -ly. As a color modifier, decorously implies a neutral-and-formal-and-proper quality where the hue carries the visual register of Edwardian-and-Victorian propriety-and-decorum-respecting coordinated formal-color-decision. Sits at the neutral-and-traditional end of the grid, parallel to properly and appropriately in usage.
Latin tenebrae, darkness — the Tenebrae service of Holy Week, where the Lamentations of Jeremiah are sung as candles are progressively extinguished, ending in total darkness. Tenebrae color refers to a Sistine Chapel-period Tenebrae service interior at the final candle-extinction: a saturated, slightly cool deep black with the matte finish of cinder-and-bone-black candle-soot on hand-finished Italian Renaissance plaster.
