Historical context

Plate 160 of Wada's 348 anchors Sulphine Yellow, Pale Raw Umber and Dark Medici Blue in the yellow 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 — Sulphine Yellow on Pale Raw Umber — reaches a contrast ratio of 2.86:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
