The cabinets in this historic home are white oak. Yes, all the trim matches the cabinets, not only the wood species, but most of the oak is from the same supplier. My cabinet maker milled all the decorative crown mouldings and shipped the same custom stain for the flat board that the contractor supplied and then stained on site. There is such a variation within the same species of wood it can be difficult to have the same stain color remain consistent even in one board. Each species of wood takes stain differently than an other. If you have nicely finished cabinets, I do recommend either staying with the same trim around the room, or going dramatically differently like a painted trim. You want to not detract from the better quality with something that might miss the mark.
