I prefer the appearance of the green top, but if your dad painted it white when nearly new, the vehicle has a family history of looking that way. That counts for something in originality if it has spent most of its life with that paint scheme. I have painted more than one roof white myself because of the heat and it makes a lot of difference. But when in doubt, and especially if they are ready to shoot white today – go with white, you can always repaint it later.

Just a note having nothing to do with your decision - at Peterbilt back in the 70’s, white was the “default” color. If the custom paint specs didn’t make it down to the paint shop in time, the truck was always painted white. Presumably this made it easier to paint it something else later.
