Usually a PPG dealer will color match in quantities of a quarter or more (unfortunately).
You also may want to try PPG Omni single stage. It is pretty glossy and very easy to use. You can always buff it out if you want more shine.

Hint: radio south r/c custom matches your colors in very small quantities. I always buy from them., specially clears (in order not to waste, which I always do when I buy full quarts!)
