Bold Karakoram

#545be4
Notes

Bold Karakoram (#545BE4) is a true blue with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (237°, 73%, 61%) 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.

Karakoram
noun

Central Asian mountain range straddling Pakistan, China, and India — home of K2 and the Hunza Valley's lapis-lazuli mines that supplied the Renaissance with ultramarine pigment. Karakoram color refers to an unworked Sar-e-Sang lapis-lazuli boulder freshly extracted from the Karakoram foothills: a saturated, slightly cool deep blue-violet with the matte finish of pyrite-flecked lazurite ore on rough fracture surface.
