I got my Title back from DMV

Guys & Gals I just received my title back from the Mo. DMV. First time in the cars whole life(46 years) that it hasn't been registered in Georgia now she has a valid Mo. registration and Title. My question is the car is sporting it's original paint other than some touch up on the sides.Myself and the wife are really enjoying the old girl and we are thinking of giving her a fresh coat of paint. With that being said do I go back with the original Plymouth color or do I paint it what ever color me and the wife decide? Changing the factory color ,how does this affect re-sale value or value in general of the car?
