Pastoral Hēi

#110018
Notes

Pastoral Hēi (#110018) 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 (283°, 100%, 5%) 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

Pastoral
adjective

Latin pāstōrālis, of-shepherds — adjectival suffix -al. As a color modifier, pastoral implies a neutral-and-shepherding-and-rural quality, the neutral color of Beethoven-Pastoral-Symphony and Constable-Stour-Valley-painting idyllic-rural-shepherding pastoral-mood color treatment. Sits at the neutral-and-traditional end of the grid, parallel to country and rural in usage.

Hēi
noun

Chinese 黑, black — the cardinal yīn color of Chinese cosmological pairing, the season of winter and the direction north in Wu Xing five-element correspondences. Hēi color refers to a Tang-dynasty hēi lacquer-coated wooden box: a saturated, slightly cool deep black with the glossy finish of multi-coat lacquer on hand-shaved cypress. Cooler than Japanese kuro.
