Let me remind everyone that we do have a superb source of color information about PRR freight cars from the 1940s and 1950s: the Grif Teller calendar paintings. Teller was a skilled and experienced artist, and knew quite well how to paint what he saw. And he often went trackside, both for ideas, and to check on the look of a painting in progress. Some have doubted the "orangey-red" of his PRR freight cars, but his paintings are pretty likely far more dependable than old slides that may or may not have been carefully stored and handled.
