The article on different color side walls is a very interesting piece of automotive history. I had seen articles of color side walls that the tire companies tried to push in mid-fifties, even saw a couple for sale. They were color coordinated to match the cars and came in the following colors, turquoise, maroon, blue and red. Everyone knows Red Line , Blue Streak , Gold Line, tires, used on different makes in the Sixties. The color side walls never caught on in the early Thirties or the Mid-Fifties, however, it is a very interesting little known fact that makes this hobby fun. Great article.
