About this combination
Combination 57 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Taupe Brown, Slate Color, as documented in the original plates.
Historical context
Plate 57 of Wada's 348 anchors Taupe Brown and Slate Color in the red family — a 2-colour grouping with a solemn, 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 — Taupe Brown on Slate Color — reaches a contrast ratio of 1.33:1, below the WCAG text-contrast floor, so it reads best in decorative blocks rather than text pairings.
