The purple seats and the table between them definitely stand out as coming from another style/era from most of the other furnishings in the room and have no corresponding colour matching in the overall colour scheme, which appears to be predominately neutrals. If using the purple seats to add colour to the room it might be necessary to add some spot colour around the room to tie it into the rest of the decor. Easy options are to add accessories like cushions, ornaments, a throw, art works or even coordinating flower arrangements
