faint indigo blue
Traditional Japanese color name for a very pale, faint indigo blue. The name literally means 'peeking into a jar', evoking the subtle blue of water or sky glimpsed inside a vessel. Historical term; not used in everyday color description.
Kamenozoki is a pale indigo color also seen in Heian-period layered garment color combinations.
The name evokes cloth given only a very brief dip in an indigo dye vat, as though it had merely “peeked into the jar,” producing an extremely pale blue.
