A named color for verdigris green.
緑青 (Rokushō) is catalogued here as verdigris green. Tobunken/CAMEO support 緑青 as malachite/green-pigment material context. HEX remains a modern display approximation, not measured colorimetry.
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.
