Historical context

Plate 189 of Wada's 348 anchors Lemon Yellow, Deep Slate Olive and Venice Green in the yellow family — a 3-colour grouping with a refined, cool 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 — Lemon Yellow on Deep Slate Olive — reaches a contrast ratio of 11.15:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
