Hi Grace Libardi, Your custom units are looking great! Are you installing a countertop as well? If you are, I would suggest to do a white countertop w/ a stained cabinet. If your not installing a countertop, I would paint it white w/ hardware to match the same color as your french doors (looks like black). Feel free to message us if you have any further questions. Thanks, Kalu Interiors
