I looked at the picture on my desktop and it's definitely blue. I don't know what you guys are smoking.
The best approach would be to get a color card and compare. Here's a screenshot of paintref.com's listing for 1950 Chevy Trucks.
Based on that, I'd say that Windsor Blue is the closest, although Seacrest Green is the same intensity.
Standby and I'll paste a couple samples on Shade Baby's picture for comparison.
[On edit] OK I guess I was smoking something funny. Seacrest Green is the closest match that I see.
