click on the flag or press space wip- not all images are centered yet There's four colors for those who need it (like oricorio, who can change forms and therefore would be one character so you need a color for each form) If the pokemon does not have that many colors, you can find a way to use them with the extra attribute you get (example: if they wear a top hat, make the top hat one of the extra colors) and/or just pick and choose which ones you want to use and which to exclude.
