Hydrangea Red & Sulphine Yellow +1

Combination 142 of 348 in Wada's six-volume 1933 work. A 3-colour grouping of Hydrangea Red, Sulphine Yellow, Salvia Blue, as documented in the original plates.

Historical context

Plate 142 of Wada's 348 anchors Hydrangea Red, Sulphine Yellow and Salvia Blue in the red 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 — Hydrangea Red on Salvia Blue — reaches a contrast ratio of 2.54:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
