About this combination
Sora-iro is the clear, bright blue of a winter sky over the Kanto plain. Shu is the sacred vermillion of torii gates at Shinto shrines. Together they compose the exact visual of a New Year's shrine visit — expectation, prayer, cold air.

Historical context
This combination from Wada's catalog anchors Sora, Shu and Gofun in the blue family — a 3-colour grouping with a bold, cool, 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 — Shu on Gofun — reaches a contrast ratio of 3.76:1, usable for large text but not body copy, so it reads best in decorative blocks rather than text pairings.
