Solemn Mauritius
Solemn Mauritius (#064F1C) is a deep green 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 (138°, 86%, 17%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin sollemnis, consecrated / annual. As a color modifier, solemn implies a deep-and-formal seriousness where the hue carries ceremonial weight, used in requiem-and-vespers religious-textile contexts. Sits at the deep-and-formal end of the grid, parallel to grave and austere in tone.
The Indian Ocean island east of Madagascar — and the saturated turquoise of Mauritian lagoon water at Le Morne and Tamarin Bay. Mauritius color refers to a Mauritian lagoon at midday: a saturated, slightly cool deep blue-green with the optical clarity of warm Indian Ocean water.
