A named color for white oak.
白橡 (Shirotsurubami) is catalogued here as white oak. Tobunken records 白橡 and related terms (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.
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.
