If the studios would do something besides flooding the arena with all that light the regular pool ball colors would be just fine, with the tv balls one more way to make a buck.
Watching pool it's often difficult to distinguish
the dark balls (2, 8, and sometimes surprisingly even the 6 and 7 - purple 4 would fall in that category as well) and
the redish balls (3, 5 and pink 4 ball).
