Fix you mean following the colors of a standard billiard?

Yes, for example I expected the 8 ball to be black.

Ok, is this the same in every country? I use to play sinuca in a bar which I know is different than other types

I found this: https://en.wikipedia.org/wiki/Billiard_ball

I expect most people to expect the "pool" ball coloration.

Thank you. I'm already in bed, but tomorrow I'll adjust the colors
