An official contest sponsored by Clip Studio Paint which was held from November 1st to November 22, 2023. During the contest, the lineart of several Shiny Colors illustrations from the game were made available to download. To compete, fans would have to choose one of the illustrations and recolor them however they wanted. To qualify, you'd need to post your work and tag it as #第二十六回塗りマス.
