Pure Manchuria

#3960bc
Notes

Pure Manchuria (#3960BC) is a true azure 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 (222°, 53%, 48%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Pure
adjective

Latin purus, clean, unmixed — applied to color since antiquity for hues that contain only one pigment without dilution by white, black, or another color. Pure red is the textbook ideal: high saturation, mid lightness, no shift. Sits at the bold-bucket center, parallel to true and strong.

Manchuria
noun

The northeastern Chinese region — historically the homeland of the Manchu people — and the deep blue of Manchurian winter sky and the Songhua River at Harbin. Manchuria refers to a Harbin Ice Festival ice sculpture in Manchurian midwinter sky: a saturated, slightly cool deep blue.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
