About this combination
Combination 72 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Sulpher Yellow, Pale King's Blue, as documented in the original plates.
Historical context
Plate 72 of Wada's 348 anchors Sulpher Yellow and Pale King's Blue in the yellow family — a 2-colour grouping with a serene, cool, austere 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 Pale King's Blue — reaches a contrast ratio of 1.34:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
