I understand this situation as I used to have MIL say alot. I do get angry n frustrated too coz we r the center person. n it's rude also to tel MIL off or tel husband how his mother really is behind him.. maybe what u can do is do a plan on what color or things u want on your own house n then show him n see what he says. if he says ok nice , we can do that, then your good . of he say no, have to see what MIL say then maybe it's time u tel him politely about your part of now MIL will hesitate to do this n that for the house when he's not home. or other option is do not tel your husband about it but talk to your MIL nicely about how you feel. hopefully she will understand.
