Peaceful Gentian

#306661
Notes

Peaceful Gentian (#306661) is a deep teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (174°, 36%, 29%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Peaceful
adjective

Latin pāx, peace — adjectival suffix -ful. As a color modifier, peaceful implies a clear-and-restful-and-calm quality where the hue carries the visual register of Quaker-meeting-house still-and-meditative interior atmosphere. Sits at the crisp-and-calm end of the grid, parallel to serene and placid 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.
