How many points do you get if you pot all the colours excluding red in a game of snooker?

The colours have the following value

Yellow - 2

Green - 3

Brown - 4

Blue - 5

Pink - 6

Black - 7

The last red has to be potted before starting on the colours.

27 is the value of the colours potted in order without missing one.

The highest score is normally considered as 147 (potting all 15 reds followed by a black on every red and then the colours) but it is possible to score more than this if your first shot is due to a foul by your opponent.
