About this combination
Combination 109 of 348 in Wada's six-volume 1933 work. A two-colour pairing of Pale Lemon Yellow, Blackish Olive, as documented in the original plates.
Historical context
Plate 109 of Wada's 348 anchors Pale Lemon Yellow and Blackish Olive in the yellow family — a 2-colour grouping with a refined, 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 — Pale Lemon Yellow on Blackish Olive — reaches a contrast ratio of 7.17:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
