Suffused Hokkaido

#373381
Notes

Suffused Hokkaido (#373381) is a true 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 (243°, 43%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Suffused
adjective

Latin suffundere, to pour beneath — past-participle of suffuse. As a color modifier, suffused implies a deep-saturation-and-warmth where the hue has been infused with pigment from within. Sits at the deep-and-saturated end of the grid, parallel to infused and warmer than drenched.

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.
