Workmanlike Gentian

#259f9c
Notes

Workmanlike Gentian (#259F9C) is a true cyan 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 (179°, 62%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Workmanlike
adjective

Old English weorcmann, workman — adjectival suffix -like. As a color modifier, workmanlike implies a clear-and-skilled-and-honest quality where the hue carries the visual register of journeyman-craftsman careful-and-competent hand-built craft. Sits at the crisp-and-functional end of the grid, parallel to functional and practical in usage.

Gentian
noun

The genus Gentiana — Alpine and high-meadow perennials whose deep saturated blue flowers are among the bluest in the European flora. Gentian-blue names a color category. The color refers to a fresh G. acaulis (stemless gentian) in Alpine meadow: a saturated, slightly cool deep blue with the matte finish of trumpet-shaped flower.
