About this combination
Combination 69 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Warm Gray, Black, as documented in the original plates.
Historical context
Plate 69 of Wada's 348 anchors Warm Gray and Black in the neutral family — a 2-colour grouping with a solemn, 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 — Warm Gray on Black — reaches a contrast ratio of 7.29:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
