The pics I've seen of the Graphite Shadow are really sharp. Same goes for the regular silver ("Liquid Platinum"), the same color as my current G37s. I think the Graphite Shadow is my second-favorite color on the car. It might even be my favorite, but the last five cars we've had in the family have been silver, black, gray, white, and silver. Not a single tinge of color in there.
That drove my decision to the Hagane Blue on my car, aka Azure Silver here in the U.S. -- it's not an overpowering shade, more like a tinted silver. I hope I'm right on that.
