Veiled Konpeki

#374d5f
Notes

Veiled Konpeki (#374D5F) is a deep 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 (207°, 27%, 29%) places it in the muted band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Veiled
adjective

The past participle of veil, to cover — used as a color modifier since the seventeenth century for hues that read as if seen through a thin layer of fabric or mist. Veiled pink, veiled lavender: low saturation combined with the optical haziness of a slight obstruction. Sits across the hushed and pale buckets alongside gauzy.

Konpeki
noun

Japanese konpeki (紺碧) — the saturated deep azure of clear ocean and sky. The compound combines kon (deep blue) and heki (jade-blue), naming a color deeper than aozora and brighter than ruri. The color refers to konpeki-painted Edo-period folding screens: a saturated, slightly cool deep blue with the matte finish of pigment in tempera.
