About this combination
Ukon is the yellow extracted from turmeric root — used to dye baby clothes and protective wrappings. Ai is the workhorse blue of every farming village. Together they are the most common and most honest textile pair in Japanese rural history.

Historical context
This combination from Wada's catalog anchors Ukon, Ai and Kinari in the yellow family — a 3-colour grouping with a earthy, warm, playful character, recorded in the Edo-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 — Ai on Kinari — reaches a contrast ratio of 9.50:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
