Paint job question

So I've come up with a two tone paintjob that I want to do, but can't come up with an idea for what color of blue to use as my 2nd color. I thought about keeping it "all original" and going with black as my primary (since the car is black), and electric blue as my secondary.

I don't want to go with a light blue, it should be something fairly darker. I've seen some very nice looking E-blue Srt's out there and this is going to be a custom paintjob so I'm debating if I want to really use the E-blue or not....

Any suggestions? I love the way AdvanSrt-4's blue looks in his sig.
