Bold Glicine

#3f3497
Notes

Bold Glicine (#3F3497) is a true blue 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 (247°, 49%, 40%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Glicine
noun

Italian for Wisteria sinensis, the cascading purple-violet flowering vine introduced from China to European gardens in 1816. Glicine color refers to a fully bloomed Glicine raceme on a Tuscan pergola: a saturated, slightly cool deep blue-violet with the velvet finish of dense pendulous wisteria racemes. Stocks as a fashion-color name in early-20th-century Italian millinery and Liberty-style enamels.
