I first heard about this at the Petrol Pumper, a truck stop and Embers Restaurant located at the junction of Highways 52 and 55. Some fella sitting at the counter was talking to two truckers. I really wasn't paying any attention until he claimed that California was outlawing black paint. My first thought was somebody was listening to Right Wing radio for more than the recommended daily allowance. But, instead of outright dismissing his statement, I decided to engage The Google.

What do you know. He's right. Sort of. It seems that by initiating solar reflection standards, California might be outlawing black paint on vehicles.

(SciGuy) California's new "Cool Cars Measure" (see .pdf of proposal) may ultimately lead to the removal of black cars from the state's highways. Cars with darker paint absorb more heat, and therefore their occupants are more likely to crank up the air conditioning. So, to cut carbon dioxide emissions, the state:

• Proposes to reduce carbon dioxide emissions by reducing interior temperatures of parked vehicles

• Reduced interior temperatures can reduce a/c capacity and likelihood of a/c use

• Smaller a/c or less operation results in less fuel used

• Less fuel used results in less vehicle carbon dioxide emissions

The aim is to reduce the state's carbon dioxide emissions to meet California's goal of cutting emissions by 25 percent by the year 2020. And black paint does not reflect enough heat to meet the new standards.

It's not that black paint is directly outlawed, though.

(AutoBlog) According to Ward's, suppliers have reportedly been testing their pigments and processes to see if it's possible to meet CARB's proposed mandate of 20% solar reflectivity by 2016 with a phase-in period starting in 2012, and things aren't looking good. Apparently, when the proper pigments and chemicals are added to black paint, the resulting color is currently being referred to as "mud-puddle brown."

No doubt the science wizards of the world will unite and come up with new paint pigments that will both look black, and properly reflect the sun.

Of course, the real challenge is to create an auto paint that can reflect the sun in the summer and absorb it during the winter. Now that would be a boon for Minnesota drivers.
