The F blue is an awesome color. I love it and sometimes wish I had gotten it but I had a previous car the same color and it created too much attention and I'm not a big attention guy but if you can handle the attention, why not go with the signature color
I personally like the way the silver looks (you can really see the lines in the body). It's less subtle yet still classy and it looks really good with the gunmetal wheels.
The gray is also a good color choice (I don't think there is a bad color in the F). It's all going to depend on what you want. Maybe someone who owns a blue can chime in, or one of the dealership guys can help with your decision.
Don't know if this helps, just thought I would add my two cents worth
