墨色 (Sumi-iro) is catalogued here as ink black. Ink-stick black; foundational to calligraphy and sumi-e.
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.
