About this combination
In classical Japanese, ao covered a range from blue to green — what a modern eye would call teal. This palette pairs that ancestral ao with shiro, a bright white, for a look that reads as cleanly contemporary while staying rooted.

Historical context
This combination from Wada's catalog anchors Ao, Shiro and Sumi in the blue family — a 3-colour grouping with a serene, cool, refined character, recorded in the Heian-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 — Shiro on Sumi — reaches a contrast ratio of 17.04:1, clearing the WCAG AAA bar for body text, so it holds up for text-on-colour layouts as well as decorative use.
