A named color for dull gray.
鈍色 (Nibi-iro) is catalogued here as dull gray. Muted gray associated with mourning robes in Heian-period court vocabulary.
Name appears in at least one CC BY-SA Wikipedia traditional Japanese color list; HEX remains a Chroma Cathay digital approximation for design use.
Traditional color names predate modern screen color spaces, so this HEX value is a design approximation rather than a material measurement.
