Hi! Thanks for your inquiry - the island cabinets are made of clear alder, and we wanted a finish with a slightly gunmetal-grey undertone to coordinate with the iron hood over the range and also the hickory floors, so I custom mixed a transparent black stain with a walnut stain to get this color. If you are looking for something similar, work with your cabinet maker to do test stain samples on the same species of wood that will be used to build your cabinets to accurately test the colors before making a final choice.
