Dyed Hokkaido

#31397e
Notes

Dyed Hokkaido (#31397E) 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°, 44%, 34%) 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

Dyed
adjective

Old English dēag, dye — past-participle of dye. As a color modifier, dyed implies a hue produced by deliberate textile-coloration in multi-bath fermentation-or-mordant-fixation processes, distinguished from natural-or-incidental color. Sits at the deep-and-pigmented end of the grid, parallel to stained and pigmented in usage.

Hokkaido
noun

Japan's northernmost island, home to the Furano lavender fields cultivated since 1948 by Tomita Farm — a Japanese imitation of Provençal lavender agriculture, now a national tourist landmark. Hokkaido color refers to a Furano lavender field at peak bloom: a saturated, slightly cool deep blue-violet with the matte finish of Lavandula angustifolia essential-oil-rich bracts. Slightly cooler than Provençal lavanda.
