Olive Yellow & Sea Green +2

About this combination

Combination 347 of 348 in Wada's six-volume 1933 work. A 4-colour grouping of Olive Yellow, Sea Green, Helvetia Blue, Lilac, as documented in the original plates.

Historical context

Plate 347 of Wada's 348 anchors Olive Yellow, Sea Green, Helvetia Blue and Lilac in the yellow family — a 4-colour grouping with a refined, cool, bold 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 — Sea Green on Helvetia Blue — reaches a contrast ratio of 2.78:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
