Options are a bit limited. The conventional tennis balls we carry are all optic yellow. We do have some colored balls, but they are all either low compression balls or pressureless—neither of which are really recommended for regular play. Low compression balls are designed to bounce lower and move slower than normal tennis balls and are intended for use as a training tool with young players. Pressureless balls don't have compressed air in the core and will never go dead, but generally they use a stiffer rubber shell to get the proper bounce. This makes them perfect for ball machines, but it also tends to make pressureless balls stiffer, heavier, and a bit harder on the arm. If you do end up opting for a pressureless ball, the Tretorn Micro-X Two Tone balls (http://www.holabirdsports.com/tretorn-micro-x-2-tone-bag-of-72.html)
play more like a conventional tennis ball.
