Name that color! I'm blazer color picking on some paint and love this one!

[SlowYourRoll]

Anyone have any idea what color this is? I just bought a 71 blazer (used to have a 71 c10 in my avatar and always wanted a blazer), but she will need to be sprayed. Instead of just looking at colors I like, I decided to google image blazers so I could see the color on the trucks. I found this as an image but couldn't get much for details on paint other than that it is a PPG color. Also, noob question, but what is the difference between the CST blazer and how will I know if I got one? It's a K5 4wd 350/350. Thanks for your help!
