1. In snooker , any of the object balls that are not reds. A colour ball must be potted after each red in the continuation of a break , and are re-spotted until the reds run out , after which the colours must be potted in their order:

* yellow (2 points);
* green (3 points);
* brown (4 points);
* blue (5 points);
* pink (6 points);
* black (7 points).

Although the full term includes "ball" after the colour, they are most commonly referred to with the omission of "ball", just stating the colour (e.g. "he's taken five blacks with reds so far").

A complete set of snooker balls with 15 red balls, six coloured balls and cue ball .
