Considerate Truffle

#190021
Notes

Considerate Truffle (#190021) 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 (285°, 100%, 6%) 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

Considerate
adjective

Latin cōnsīderātus, thoughtful — past-participle of consider. As a color modifier, considerate implies a neutral-and-thoughtful-and-careful quality where the hue carries the visual register of careful-and-thoughtful-and-considerate coordinated color-decision matched to its surroundings. Sits at the neutral-and-friendly end of the grid, parallel to thoughtful and mannerly in usage.

Truffle
noun

Eurasian Tuber melanosporum (black Périgord truffle) — an ascomycete hypogeous fungus that grows in symbiosis with oak-and-hazel root systems on chalky calcareous soils, harvested with truffle-trained dogs in Périgord and Umbria. Truffle color refers to a freshly sliced Tuber melanosporum cross-section on a wooden cutting board: a saturated, slightly cool deep black with the matte finish of marbled black-and-white-veined fungal-tissue.
