About this combination
Combination 84 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Seashell Pink, Deep Slate Green, as documented in the original plates.
Historical context
Plate 84 of Wada's 348 anchors Seashell Pink and Deep Slate Green in the orange 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 — Seashell Pink on Deep Slate Green — reaches a contrast ratio of 10.45:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
