Henry Ford supposedly said of the Model T, “You can buy it in any color, as long as it’s black.” In fact, before 1913 the Model T was available in red, gray, green, and blue. For the thirteen years following 1913, indeed black was the only color. Then, in the last two years of its product life, the Model T was available in 11 colors. Ford’s design decision relative to paint colors was the response of a producer to economic factors of both supply and demand.
