Aside from taste, does the color of your car matter? Can it have any influence over anything? Recall that light colors reflect more light than dark colors. This means that a car in strong sunlight with a dark paint job will get hotter than a light painted car. In the heat of a sizzling summer, the difference might be quite a bit. On other days, the difference might be enough to make you decide between switching on the air conditioning or not. And if the air conditioner is on, a light paint job will make its job slightly easier.
The air conditioner burns extra gas every minute it is running. So using the air conditioner less will save on gas. So if you are interested in saving on gas, especially if you live in a hot and sunny place, choosing a light colored vehicle could help you out.
