Bold Outremer

#374eac
Notes

Bold Outremer (#374EAC) 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 (228°, 52%, 45%) 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 amber. 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.

Outremer
noun

The French word for ultramarine — literally beyond-the-sea, naming the lapis-lazuli pigment imported from Afghanistan via Mediterranean trade routes. Outremer names the same pigment as English ultramarine but with the French Renaissance-and-after register. The color refers to a freshly mixed outremer pigment in oil: a saturated, slightly violet-shifted deep blue.
