About this combination
Combination 74 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Turquoise Green, Green Blue, as documented in the original plates.
Historical context
Plate 74 of Wada's 348 anchors Turquoise Green and Green Blue in the green family — a 2-colour grouping with a refined, 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 — Turquoise Green on Green Blue — reaches a contrast ratio of 2.59:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
