Homespun Hauberk

#0a1231
Notes

Homespun Hauberk (#0A1231) is a deep blue with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (228°, 66%, 12%) 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

Homespun
adjective

English compound home + past-participle spun — sharing root with spin. As a color modifier, homespun implies a neutral-and-cottage-industry-and-traditional quality, the neutral color of Welsh-and-Scottish-Highland hand-spun-and-hand-woven cottage-industry-and-traditional-craft textile-finish. Sits at the neutral-and-traditional end of the grid, parallel to folksy and homey in usage.

Hauberk
noun

Old French hauberc, neck-guard — the medieval European mail-armor knee-length tunic worn by mounted knights, woven from interlocking iron rings. Hauberk color refers to an English Plantagenet-period chain-mail hauberk in raking light: a dark cool-gray with the matte finish of iron-and-rust-patina interlocking forged ring-mail on dark hand-dyed gambeson underpadding.
