Chrysler told dealers it was restricting orders on vehicles in 10 colors, including two variations of black and three of red. Ford is slowing production of vehicles in "tuxedo black" and three variations of red.
Chrysler spokeswoman Katie Hepler called it a "precautionary measure" and said the company did not expect any effect on production at this time.
"We anticipate that we currently have an adequate ... supply to meet existing customer orders," Hepler said in a statement.
She said other colors being restricted were Bronze Star, Rugged Brown, Hunter Green, Ivory, and Billet Silver.
