> Grey/Silver color range is much easier to keep clean, and stays cooler in the sun. That's true, however there's also a surprisingly big drop in reflectance going from white (~85%) to even a light gray (~50%). Now these figures are for "normal" flat paint used for steel construction, the glossy metallic paints used for cars probably have higher reflectances. But still.
