I'm going through the same thing right now. I went to the paint store today with my wife to get her opinion on the colors I have narrowed it down to. I would suggest you decide on the basic color first, then develop a list of that basic color that have potential. At first I was going to paint it something other than blue but that's always been my favorite, and I just kept going back to it, so I gave in. A friend suggested not to rely on pictures on the Internet, they are not the same in real life. Man was he right.

If you are interested in Blues these are the colors I have narrowed it down to for me.
2007 Toyota Tundra Blue Streak Metallic code 8T7
2011 Mazda Sky Blue Mica code 41B
1997 Dodge Viper GTS Codes PBE and SBE one is lighter
2006 Dodge Nitro Electric Blue code PB5
unk year BMW X5 Lemans Blue code 381
2007 Pont. GTO Impulse Metallic code WA938J

This is tuff!
Good luck.
