I am not able to get undercabinet lighting in my kitchen. I do plan to get track lighting in the ceiling. Right now most of the time, my Uba Tuba granite appears somewhat solid and dark green/black in color. However, during certain times of the day, when the natural lighting changes, the countertop explodes with color definition - greens, golds, silver!!! What is the best "type" of overhead track lighting to get that will bring out the awesome colors of Uba Tuba??? Help!!!
