Re: Horizon Blue
What I also suggest to people who are thinking about going with a custom color is (1) go with a color that Porsche has done before sometime and (2) order a tube or can of it from Paintscratch.com or any other competent paint company so that you can see it in real life. $10 is cheap insurance to find out if its a color you will like. Spray that on a large board for yourself to evaluate.
