Canvas 2: Niji-iro no Sketch, ef: A Tale of Melodies. Recommendations
Both contain a character with painful memories and them dealing with it by avoiding some sort of art, whether its musical or visual. The same mood gets sent whenever both shows start digging into the past and each give hint by hint to what happened.
In both stories there is a talented painter that cannot paint cause of a painful experience.Futhermore both animes are Drama-Romance type.Although, Ef is a much better anime overall.
