Makes we recall the reason given for selecting the color for the "walking beam" on the San Francisco paddle-wheel ferryboats. At one time they were painted black and then one of the boats had the big “walking beam” casting break causing a whole bunch of damage – it was determined that the casting had had an undetected crack. Very soon all of the “walking beams” were painted white -- to make cracks visible.
