If everything about the picture quality and ease of use is the same then go with the color that is cheapest. Whats more important to you? What it does or how it looks? Reminds me of a girl I know who will not buy a car of a certain color because either it shows dirt or she doesn't like the exact shade of color. She doesn't appreciate that whatever color it is what matters is how the car works and runs and uses gas. Color is just an added thing and who wants to pay more just for a color case?
