Lots of luck. I tried 5 times to match it using colors off the various sites (this old game and prok's site have some) and wasn't even close. I gave up and sold my Moon Patrol. I have been told that if you can get down to an automotive paint shop they have some tools that can make an exact match by scanning a piece of the side, but I have not tried that.
There is no exact. All depends on your cab, what paint they used at the time, how yellowed it got with age, how it was maintained.. one may be bright blue, one may be yellowish blue.
