From Green Hell,  New green target: Car colors

Automakers say such a regulation would:
* Eliminate a significant number of vehicle colors (e.g., black paint and dark metallic colors would essentially be banned, representing 40 percent of sales for some manufacturers);
* Raise costs for manufacturers and consumers — about $1.2 billion annually; and
* Increase CO2 emissions because of forced changes in the painting process and increased vehicular weight.

Good grief.
