Black Isn’t The New green
California considering ban on black paint
Jet-black automotive paintjobs could be regulated out of existence in the US if proposals under consideration by the California Air Resources Board are followed through.
Apparently the CARB is getting hot under the collar about the extra carbon being consumed by California residents turning-up the air-con to cool their sun-drenched black cars. The Board has already set new rules in place that will force manufacturers to increase the solar reflectiveness of future paint coatings, as well as improve the thermal efficiency of automotive glazing. It believes more stringent rules in this area could save nearly a million tons of CO2 per year by 2020.
However, according to Autoblog in the US, paint companies are struggling to make a decent black finish that meets the forthcoming requirements for 20% solar reflectivity by 2016 – the best attempts so far being a sort of sludgy brown.
Autoblog has noted the possibility that this story is an elaborate – if early - April Fool, but CARB has produced a 36-page treatise on the subject. As we know, where California leads in the field of ‘cleaning-up’ the automotive sector, others tend to follow. Interested parties can read all about the CARB ‘cool cars’ program here.
Black is the perfect light absorbing colour - that's why it looks black - no light is reflected from it. White is the highest reflectivity colour because it reflects all visible light components away from itself and we do not see any colour tint (not even a sludgy-brown sort of white). More light absorbed means more heat to neutralise with aircon.
To me it makes perfect sense to stop the deliberate creation of cars that need aircon running flat out throughout daylight hours for much of the year. In the UK most summers it makes little difference what colour car you run. Rain is uncaring on the matter... but in the summer of 2006 (the hot one) I regretted enormously running a black car with black leather interior, whose aircon was to say the least somewhat knackered!
When I've worked or holidayed in California that option has never occurred to me. Palm Springs in summer means a white car in my humble opinion. Thank God it is easy to hire one as they are so popular. I would run a mile from a black one even for a week's hire...
So, for once I support the efforts of officialdom...

. No wonder that California is facing such a massive deficit.
