We took down a very non-functional microwave cabinet and carpenter coming tomorrow to install 3 wooden open shelves that will attach to the cabinet and angle around the corner and over to the adjacent edge of wall. Should the shelving finish be stained to match cabinets? Or should I paint them white like the trim work? What if I stained the brackets and painted shelving white or painted the brackets and stained the shelving?(something like the stairway finish in the back-ground)

The bottom shelf will line up to the second shelf of the existing cabinet and I am also adding white subway tile up to that point.
Please help me decide! All along I thought I was going for full white, but now I'm not sure how it will look next to the cherry cabinet! I will be displaying all white Fiestaware on them....
