Utilitarian Forgetmenot

#3da6b1
Notes

Utilitarian Forgetmenot (#3DA6B1) is a true cyan 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 (186°, 49%, 47%) 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

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.

Forgetmenot
noun

Myosotis sylvatica, the European forget-me-not — a small woodland-and-streamside wildflower whose pale blue five-petaled flowers symbolize remembrance and faithful love in European folk tradition. The color refers to a fresh forget-me-not flower: a soft, slightly cool pale blue with the matte finish of small five-petaled flower with yellow center.
