We have a small room over the garage that we are going to use for our kids game/guest room. It will be more on the adult side but will be friendly for the kids. I am using pieces from Target and West Elm to decorate it in MCM. We have bead board that my design friend recommended we get rid of but we found out from the previous owner that there is no sheetrock behind it, only insulation. We have too many projects to delve into that right now. My question is, should we paint it the same color as the walls? It will be a taupey/grey color not the color seen here. I've attached a few pics of some the decor we are using too.

Thank you!
