It is a great color choice, but I have to throw some clarification in the mix...
- Paint Code: 5707 is "Aquamarine Blue"
- Paint Code: 5606 is "Aquamarine Blue Metallic"
They are very two different colors. The 5606 is a lighter shade of blue and has the metallic flakes that sparkle in the sun. 5707 is a flat blue - which I believe is similar to the picture Alan posted earlier.
Here is a good reference link:

I prefer 5707, but I am bias ;-) I wanted to keep true to my build and stick to the 57 paint codes. That has gone out the window with my coupe build... LOL!
