About this combination
Combination 14 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Spinel Red, Naples Yellow, as documented in the original plates.
Historical context
Plate 14 of Wada's 348 anchors Spinel Red and Naples Yellow in the red family — a 2-colour grouping with a serene, 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 — Spinel Red on Naples Yellow — reaches a contrast ratio of 2.23:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
