COLORS is a short, Touhou doujinshi released during Comiket 76 by the relatively unknown artist Tsuki (つき). In fact, this artist is probably even more unknown due to a recent name change. Though the circle remains the same, Chikatama (ちかたま), the artist's pen name changed from Chika (ちか) to Tsuki (つき) between Comiket 76 and 77 and this doujinshi was published under the former name. Since this is a bit on the short side with just 16 pages, I also want to talk about the Touhou and Vocaloid genres in general.
