Historical context

Plate 151 of Wada's 348 anchors Sulpher Yellow, Yellow Orange and Vandar Poel's Blue 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 — Sulpher Yellow on Vandar Poel's Blue — reaches a contrast ratio of 7.51:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
