It really depends on the look you want. I used to own a bluestone G30 and loved the color. I now have a Donnington Grey F90 that I stealth wrapped and love that. It's an entirely different look once you wrap it in stealth.
Go to a shop you'd want to wrap the car with and have them put a sample of the stealth on your car. Once they did that on mine, I knew it was the look I wanted.
This thread was my inspiration and is your color.
