Glowing Manchuria

#688bfa
Notes

Glowing Manchuria (#688BFA) is a true blue with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (226°, 94%, 69%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Glowing
adjective

The progressive participle of glow, to emit light — used as a color word since the medieval period for hues that read as if they were luminous from within. Glowing amber, glowing rose: the implication is moderate saturation combined with the optical impression of internal light. Sits in the bright-bucket alongside radiant.

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.
