Which colour is used as one of the coloured balls in the game of professional snooker?

Grew up watching Pot Black.

Richard27638, But that is outside a maximum break.

Player #7719043, maximum break. Score could be higher if opponent fouls before starting maximum break to clear the table.

Twie, at this point not anymore. Most are, but some marked orange and purple (?!). I'm not English, but I've loved snooker ever since I saw a Hendry's match in early 1990s

Twiekah, Oh my goodness...on the same date I just touched the wrong button accidentally. I love snooker.

Everybody is correct at this point ;)
