In 1998, I bought an Accord in black because I thought it looked cool. Not surprisingly, it turned out to be hot anytime the sun shone. Now the paint is coming off the roof from baking for ten years, so it's time to get the Accord repainted so I can limp it along a few more years.
From a non-aesthetic standpoint, what's the best color for a car?
I see four goals:
1. Heats up the least in the sun.
2. Most visible for safety.
3. Shows dirt the least.
4. Not gaudy (i.e., not pink or purple or anything else that, as Oscar Wilde would say, might expose me to comment at the stoplight).
The EPA finally improved their Miles Per Gallon ratings about a year ago. Ever since the 1970s, they had been based on a maximum speed of 55 mph, so they were absurdly optimistic. Because car color affects gas mileage (hotter cars lead to the air conditioner being run more), perhaps the government should publish heat absorption figures for every color. (Of course, it would probably take the EPA decades to get it right.)
