Stately Hokkaido

#571f9d
Notes

Stately Hokkaido (#571F9D) is a true indigo 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 (267°, 67%, 37%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stately
adjective

An adjectival form of state, condition of dignity. Used as a color modifier since the seventeenth century for the deep saturated jewel tones of formal ceremony — the deep blue of a robes-of-state, the deep red of a state-banquet velvet. Sits in the bold-and-formal corner alongside imperial and royal, with slightly less institutional weight.

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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

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.
