If you loved The Colors Within, try K-ON! The Movie
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Naoko Yamada, and they both carry the bittersweet, tender mood tags, and they sit in Animation / Music territory. If that's the register that drew you to The Colors Within, the second film will land in a comparable space — through a different lens.
