Historical context

Plate 243 of Wada's 348 anchors Raw Sienna, Ivory Buff, Olive Green and Slate Color in the orange family — a 4-colour grouping with a refined, warm, bold 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 — Ivory Buff on Slate Color — reaches a contrast ratio of 6.84:1, meeting the WCAG AA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
