Does the Color of an HD Pickup Make a Difference?

I wish someone could demonstrate the used price differential between colors.
Is a dealer going to offer less on green trade in as opposed to a white one? If so how much?
To me logically if the second owner was that particular, he would buy new and order what he wants.
If he does not have the credit or financial wherewithal to buy new,I doubt color actually figures into the equation for the majority of second owners and none of the third.
