I scanned the PPG website for a few minutes, but didn't see anything there. I know there is a site somewhere, but if you want to get a true idea of what the paint looks like, the internet isn't the best place. A computer screen is terrible for accurate color reproduction. Head out to your local paint supplier and look at their books of colors. That's the only way to see what they will really look like. I even take the book outdoors so I can see what the sun does to it. Some things really change with different light sources.
Of course, you'll pick out a great color after days of thought, then squirt it on the bike and it will look completely different that what you had in mind. That usually happens to me, anyway.
