About this combination
Combination 5 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Cossack Green, Vandar Poel's Blue, as documented in the original plates.
Historical context
Plate 5 of Wada's 348 anchors Cossack Green and Vandar Poel's Blue in the green family — a 2-colour grouping with a solemn, 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 — Cossack Green on Vandar Poel's Blue — reaches a contrast ratio of 1.68:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
