Seven colored balls (Violet, Purple, Blue, Green, Yellow, Orange, and Red) are arranged in a row during a game. The Yellow ball is to the immediate left of the Purple ball. Violet is to the left of Blue but not between Blue and Purple. Exactly four balls are between Blue and Purple. If Violet and Green have exactly two balls between them, how many balls do Orange and Red have between them?
