don't do this, but i am painting mine a house of kolor kandy oriental blue with orion silver basecoat. It will look friggin awesome, but is a real light blue. This is a suggestion, if you don't mind it being a honda paint, but they have a stock blue that is very nice. and the corvette brilliant blue is what was on my chevy impala is darker and really nice looking to.

 

It all just really depends on you, just go to a car paint store or shop and ask to see a color book, there are thousands of blue colors from kandy to flat to pearl. just anything, also your basecoat will have an effect on the color the paint is.
