PPGs Oliver paint codes are 45132 for the green and clover white is 46536.  As I understand it PPG has various grades that you can buy with their "Concept" being the best.

Lots of guys just use AGCOs Meadow Green and Clover White.     

My brother has painted a few of the 50 series and on a couple of them he used a paint that is really white when compared to the clover white.  I like the white better.   Remember it is your tractor and you can make it look like you want (well, I wouldn't recommend John Deere yellow).  If you use the TSC paint when you are done it will be all same and it is easy to get touch up cans.  If your tractor now has the original paint it has probably faded quite a bit, even the paint on the back of tin could be different than it was from the factory due to engine heat, oil, grease, etc.
