Stained Aizu

#15153a
Notes

Stained Aizu (#15153A) 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 (240°, 47%, 15%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stained
adjective

Old French desteindre, to discolor — past-participle of stain. As a color modifier, stained implies a deep-pigment-and-permanent quality where the hue has bonded with the substrate fiber. Sits at the deep-and-pigmented end of the grid, parallel to dyed and suffused in usage.

Aizu
noun

Japanese feudal domain (Aizu-han) of the Edo period — a samurai region in modern Fukushima famous for aizu-momen, the indigo-dyed cotton woven by samurai-class women during the Tokugawa shogunate's lean years. Aizu color refers to a freshly aizu-momen-woven indigo cotton: a saturated, slightly cool deep blue-violet with the matte finish of multi-bath natural indigo on hand-spun cotton.
