About this combination
Combination 70 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Raw Sienna, Lincoln Green, as documented in the original plates.
Historical context
Plate 70 of Wada's 348 anchors Raw Sienna and Lincoln 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 — Raw Sienna on Lincoln Green — reaches a contrast ratio of 1.95:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
