Go to
this page to determine the colors and amounts to achieve the color you want. That's what I do when I seek a specific color. Once found, you might be able to take your findings to a auto paint store and have them mix up a rattle can or two for you. If you can do your own spray work, so much the better. In my case, I do my paint work with a paint brush and am always happy with the result (but i takes practice do get good at it). Anyway, thought that this might be of some help and, for what it is worth, it is kinda fun to play with.
