BTW you're allowed any contrasting colour now:
"The ball must be a rubber sphere with a uniform outer surface in white, yellow, or any other colour that provides an
appropriate contrast distinct from the colour of the playing surface."

Awesome so my neon pink balls would be legal now? I love the color and it’s easier to make sure you bring your own balls home with you if they are not the standard yellow. And they have great contrast with the blue course.
