Im completly stumped on a color choice now.
I love the ABM, and the IOM, and maybe even black.
I just painted my 68 RS SS Mystic Teal Poly (metallic)
and it looks quite the same. Depending how bright it is outside. Bright days looks almost green, and cloudy days looks dark blue. Check it out.
Also check out the ABM HHR pics:
