not sure I agree, "invisible" friend (your "light" is red)I like the white also. I didn't know about white being the color of humility but I do know it does keep the car cooler. Plus white is easier to keep clean than the darker colors. Silver is the best low-maintenance color, I think white is second.
I have seen a couple of white 430s and think it actually works quite well. Here is a recent picture of a white 430 Challenge.Well here in Maine they salt the roads in the winter to melt the ice. If you have a dark vehicle the salt dust shows up immediately. It doesn't show up on a white car. I would assume the light colored sand in Dubai would be the same. On a dark vehicle you would always see the dust, it won't really show up on a lighter vehicle.
