Racquetball color meaning?

Question

Can someone break down the speed/use of the different racquetball ball colors? I normally use green or blue (indoor use) but I heard black are the best for indoor...? Thanks.

Answer 1

i only heard once that the green has more speed and the purple even more, but i only use the blue one is the most common

Answer 2

Color of the balls doesn't matter.  The only difference is either indoor or outdoor balls :)
