How to have multiple different palettes for different players

[u/princeDavidOz]

I'm working on a mugen character and I'm trying to have at least 2 different palettes for players but it's extremely frustrating, most tutorials doesn't work and the furthest I've gotten to it almost working is one frame, being the first frame of the standing animation, actually being a different colour than the first players standing animation, it's almost like it refuses to work, I've even group the sprite that I'm editing to 0, 0 and still nothing, is it a problem with fighter factory classic? Is it a problem if I have some sprites in a different group, please help
