If you used OpenBORStats for a basic quick character making, that could mean you didn't remove the name 00.png from the coding in any of the character's animation. That's because one of the sprites doesn't have the palette uniform as the others, which is 00.png. All sprites in one folder should have the same palette. Having different palettes while being coded is included, it would mess up colors like you got. If you were to go with "Yes" (or "Yes to All" if it converts to all images in one folder) to that, the sprite should've changed its colors differently from the palette. It's not a sprite problem. It's a coding problem. Only remove the one that doesn't have the same palette as the others from your character code.
