Shadowy Karakoram

#191e4d
Notes

Shadowy Karakoram (#191E4D) is a deep 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 (234°, 51%, 20%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Shadowy
adjective

Old English sceaduwig, full of shadow — adjectival form of shadow. As a color modifier, shadowy implies a deep-and-obscured quality where the hue is partially-occluded by intervening shade. Sits at the deep-and-veiled end of the grid, parallel to shaded and cloaked in usage.

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.
