My understanding ( and I realize I may have it totally wrong)
A traditional set of pool balls was given to a lab that worked on colors and visibility and they came up with the Tournament Blue color. They did not pick this color based on what looks good. They felt this color was the best background color for the balls. Making for good contrast between balls and cloth. Not surprisingly, the color of the US Open Tennis tournament surface color is very similar to tournament blue. IMHO this is not a coincidence. This blue must give the best contrast, even for a tennis ball.
Of course now that we have all these crazy colors for pool balls. Some of which fight the contrast that is desirable for best visibility.
Just my 2 cents.
