With a non standard colour they often put thicker paint on them to get the depth of colour, but as most vans standard colour is white you don't need as thick a coat to get the depth of colour, hence why most manufacturers offer white as the standard colour, and any other colour as an option. The difference in paint consumption is minimal per unit, but add it up over a production line run and the saving soon adds up to a lot of paint saved.
are you being serious ? white takes more to cover, and darker colours have more depth hence more reflective and easier to see reflections
