Sunday Times Teaser 2484

Josh put all the snooker balls except the cue into a bag. He and I then played an imaginary frame. At each person’s turn, he drew a ball. If it was red, he scored a point, discarded the red and drew again. If that was a “colour” (not red), he scored the appropriate number of points, returned it to the bag, then tried again for a red. If a player drew the wrong ball, it was returned to the bag and his break was over. On one break, the first four balls drawn earned me points; at that stage, the chance of this happening was one in N, N being the number of points I’d got from the break so far.

Which two colours had I drawn?
