I have smokey granite IS F and it blends with the wheels. I have had many other IS F owners comment that it's probably the best combo with the wheels. I love the ultrasonic blue but in many ways it reminds me of 15 years ago when I chopped up my Honda into a "fast and furious" car. Nice color but screaming look at me!!. I don't think you can go wrong either way, it just depends on how much you want a speeding ticket color vs. a sleeper color.
