while you can't get the exact color from one can....I managed to get REALLY close to the honda candy blue-green using spraymax 2k, which I think was 3 colors originally?
I had to play with it, staring at color square sheets for days finding the "right one". then I sent the company I used a sample of nail polish that I liked and was the closest I could find. what the made and sent was wonderful. its not 100% but it's very very close. I'm not sure who you are using to get your color but I used 66autcolor.com and they were very helpful and friendly. I recently used them again for my second bike, and will be using them a third time this spring/summer
it can be done, but it's not going to be easy. the paint I got was metallic and had a good flake to it, it was not flat or pastel. I am sure that depends on what gets mixed though.
