The truth is, I haven't seen the movie (and I didn't even know it had just come out), but the concept of seeing colors in people's personalities seems beautiful and incredibly poetic to me.
I love these slice-of-life stories where people come together to form a band; I feel like they always manage to convey a lot of emotion, especially with that theme of pursuing dreams despite what parents or society expect, which is something easy to relate to. Thanks for the recommendation! I'm adding it to my list to watch as soon as I can.
