Well, it took almost a month longer to get it than it should have (USPS/Canada Posts fault though! It was postmarked July 3) but I will agree, I think it is too grey for my liking as well. I noticed the link at the top is dead, but it looked pretty close to what the decals really are (going by memory).
ALTHOUGH, when I build the model I am going to paint the belly and "dark" tiled areas black in hope of darkening the decals a bit, but I am not sure how optomistic I should be.
I will use the decals for sure though as they are an incredibly detailed set. The color is just a titch to grey for my liking.
