Historical context

Plate 170 of Wada's 348 anchors Rosolanc Purple, Orange Yellow and Red Violet in the pink family — a 3-colour grouping with a refined 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 — Orange Yellow on Red Violet — reaches a contrast ratio of 6.11:1, meeting the WCAG AA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
