Looks to me like it's PPG paint (sorry I couldn't resist).
KM-47 and RCDSO "look" like Ford colors.
WB-13g might be added to the KM-47 as the formula for a custom color but can't say for sure.

Is the truck blue/green?

My suggestion is take this information to PPG automotive body shop supplier and they will likely decode it for you.
