About this combination
Combination 73 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Pale Raw Umber, Rainette Green, as documented in the original plates.
Historical context
Plate 73 of Wada's 348 anchors Pale Raw Umber and Rainette Green in the orange family — a 2-colour grouping with a refined, warm, 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 — Pale Raw Umber on Rainette Green — reaches a contrast ratio of 2.57:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
