Historical context

Plate 259 of Wada's 348 anchors Lemon Yellow, Green Blue, Helvetia Blue and Warm Gray in the yellow family — a 4-colour grouping with a refined, cool, 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 — Lemon Yellow on Helvetia Blue — reaches a contrast ratio of 5.97:1, meeting the WCAG AA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
