紫紺色Shikon-iro
しこんいろ · Purple navy · family purple
A named color for purple navy.
紫紺色 (Shikon-iro) is catalogued here as purple navy. Tobunken records 紫紺 in Nara-period color vocabulary (historical name attestation). No standard measured sRGB/Lab value tied to this exact historical usage is currently available; HEX is a modern authoritative approximation.
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.
Traditional color names predate modern screen color spaces, so this HEX value is a design approximation rather than a material measurement.
