Sensibly Mouse
Sensibly Mouse (#1D0530) 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 (273°, 81%, 10%) 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
Latin sēnsibilis, perceivable / having-good-sense — adverbial-and-adjectival suffix -ly. As a color modifier, sensibly implies a neutral-and-practical-and-rational quality where the hue carries the visual register of practical-and-functional color-decision matched to its everyday-use context. Sits at the neutral-and-traditional end of the grid, parallel to reasonably and practical in usage.
Eurasian Mus musculus — the Muridae commensal-rodent species adapted to human domestic-architecture, with the iconic deep-cool-gray mouse-gray dorsal-coat color. Mouse color refers to a Mus musculus dorsal-fur field in raking light: a dark cool-gray with the matte finish of agouti-banded melanin-pigmented short-undercoat-and-guard-hair fur.
