The colour of the ball

Why would one want orange balls?
They are,at least for me,simply too dark.

Everybody misses the orange balls. The white ball is invisible when it's out of the table.

Which company will be the first to make orange balls?

We use orange balls at the office because the walls are white (and close) and white balls 'disappear' into the background. I use them at home for my practice balls too, for a similar reason.  The table at work is black, the one at home green so either colour works fine over the tables.  The club tables are blue and the background (walls) are so far away it wouldn't matter what balls we used but we use white balls. There is definitely a time and place for each.

DK, I'm not sure dual colour balls will be very effective.  I have some at home for service spin practice and occasionally we try to play with them.  They are actually very difficult to track, especially in terms of their 4-dimensional position -  you can see the ball but depth perception and therefore contact timing is very tricky.

In my opinion, orange balls could come back into local league level but not pro

In my opinion I think white balls look more professional than orange. Orange seems a bit cheap and unprofessional
