About this combination
Combination 89 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Yellow Orange, Violet Blue, as documented in the original plates.
Historical context
Plate 89 of Wada's 348 anchors Yellow Orange and Violet Blue in the yellow 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 — Yellow Orange on Violet Blue — reaches a contrast ratio of 4.33:1, usable for large text but not body copy, so it reads best in decorative blocks rather than text pairings.
