The linear velocity at the edge of a six foot diameter disc:

V = 1440 x 6 x 3.14
V = 27130 feet per minute
V = 4.7 miles per minute
V = 283 mph.

If you blow up the photo that is pretty much what the sign is displaying. I think it is possible that this was actually meant to demonstrate how impractical a color wheel system was.
