About this combination
Combination 20 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Calamine BLue, Laelia Pink, as documented in the original plates.
Historical context
Plate 20 of Wada's 348 anchors Calamine BLue and Laelia Pink in the blue 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 — Calamine BLue on Laelia Pink — reaches a contrast ratio of 1.40:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
