When I picked the color for my Eisentraut, he wanted the PPG #... I finally hit pay dirt in Colorado Springs buy visiting car paint retailers (look under auto painting I think and the ads will say "PPG"). These places have tons of paint chip books that lists all car colors, samples, and the PPG #. I found the PPG web page but they didn't have the color charts on-line.
I pretended I was going to repaint a motorcycle because the first place I mentioned a bicycle to didn't take me seriously and said "it's expensive, sure you don't want Rustolium?" Anyway, I just used their vast books to look at every color from every car maker for the last 10 years, what choices they offer!
Cobalt sounds awesome, I went with a BMW blue/gray met. that was closest to what I was looking for. Good luck!
