縹色Hanada-iro

はなだいろ · Bright indigo · family blue

A named color for bright indigo.

縹色 (Hanada-iro) is catalogued here as bright indigo. Mid-range indigo; one of the oldest Japanese blue names.

Tobunken records the underlying color/material term in the Nara-period vocabulary database derived from 『大日本古文書』; this supports historical name attestation, not measured sRGB.

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.
