Historical context

Plate 183 of Wada's 348 anchors Deep Violet / Plumbeous, Veronia Purple and Red Violet in the neutral family — a 3-colour grouping with a refined, warm character, recorded in the Showa-era volumes of Sanzo Wada's 1933 Dictionary of Color Combinations, where these shikisai names have sat in the public domain for generations. Its strongest pairing — Deep Violet / Plumbeous on Red Violet — reaches a contrast ratio of 2.31:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
