MDtech, you can also change the hardware on your cabinets, depending on the granite you get
and depending on the general style of your home.
Adding pictures, accessories, rugs, and kitchen top appliances in the general theme color you choose will also help a lot.
I don't know why you say you are
bad with colors - they are just your choice and you should not let anyone tell you otherwise
Pick YOUR favorite colors, take a samples of those and put them each next to the granite you like with a piece of something white. And voila, you will have your favorite color pallets to compare!!
