Established Hokkaido

#3d40c0
Notes

Established Hokkaido (#3D40C0) 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 (239°, 52%, 50%) 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

Established
adjective

Latin stabilīre, to make stable — past-participle of establish. As a color modifier, established implies a saturated-and-rooted quality where the hue carries the weight of long-standing visual presence. Sits at the bold-and-firm end of the grid, parallel to steadfast and anchored 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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
