Hollowed Lāzhuward

#1f374b
Notes

Hollowed Lāzhuward (#1F374B) is a deep azure 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 (207°, 42%, 21%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Hollowed
adjective

Old English holh, hollow — past-participle of hollow. As a color modifier, hollowed implies the deep-and-cavernous-and-architectural quality of carved-out-cave-and-tunnel interior, particularly the Cappadocian and Lalibela hand-carved rock-cut churches and underground cities. Sits at the deep-and-architectural end of the grid, parallel to cavernous with hand-carved register.

Lāzhuward
noun

The Persian word for lapis lazuli — the etymological source of every Western language's word for azure (Arabic al-lāzaward → Old French azur → English azure). Lāzhuward names the stone mined from the Sar-e-Sang valley of Afghanistan. The color refers to a polished Afghan lapis cabochon: a saturated, slightly cool deep blue with the matte finish of high-grade lapis.
