赤橡Akatsurubami

A named color for red acorn brown.

赤橡 (Akatsurubami) is catalogued here as red acorn brown. Tobunken lists 赤橡 in the Nara-period color/material vocabulary as an oak/acorn dye variant (historical name attestation). HEX is a modern authoritative approximation, not a measured textile sample.

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.
