Having played this game for a year I've noticed a lack of color variation in certain outfits. I can understand a part of the scratch experience is vying for the outfit with a particular color that you want, however outfit variants seem to be limited to just a few color schemes: Snow, Shadow, and Ruby are the most likely alternates. Only outfits that are purchased from the shopping plaza or obtained from the mission pass seem to have customizable colors for non-casts.
That being said, in most other games I like my characters to be wearing greens and yellows as those are among my favorite colors. The only time I can have a green or yellow outfit in the game seems to be if that is that outfit's base color, or I get an outfit on mission pass or the shopping plaza and use a color change pass in the solon. It might not be a breaking point, but it does hurt that I cannot customize my character the way I want to.
