Hey PvtDet,
I just shot my roadking Black Sparkle Pearl and flamed it with HOK Kameleon Pearl Flake Red to green. It is subtle, but it looks different at different angles. I am getting ready to shoot the final clear coats and buff it out. It looks completely outstanding so far. You might try this idea out. Also, they make Green to gold, Blue to green, and Sapphire (I think this changes from light blue to deep blue) in the Kameleon Pearl. Check them out. Good luck.
On the chop, I personally would go with something that is "in your face". Even slow choppers should grab peoples attentions... Just my opinion. Take it easy.
