I'm doing that cabinet color remodel currently & I also have white trim around windows & floors. But my decorator asked me this question " if you were going to do dark cabinets ---- would you change all the trim in your house to match the dark cabinets? No". I think it will look fine!!!!! My kitchen is a little separated from most of the white trim..... But I have a pantry door that will remain lighter than my cabinets. Good luck!
