Utilitarian Glauque

#3b6074
Notes

Utilitarian Glauque (#3B6074) is a deep azure 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 (201°, 33%, 34%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

Glauque
noun

The French adjective for gray-blue-green — borrowed from the Greek glaukos, the epithet of the goddess Athena's eyes (glaukōpis). Used in French color vocabulary for the cold gray-blue of stormy seas and aged metal patina. The color refers to a cold Atlantic morning at Pointe du Raz: a soft, slightly cool deep gray-blue-green.
