The position below is from a rapid game I played on lichess.org against a lower-rated player. And look how he escaped with a draw thanks to opposite colour bishops. So remember, you can save a difficult position by achieving opposite colour bishops.
Black has no way of forcing the White King to move so the passed pawn is stalled; and there is no way to attack the White pawns. So White simply shuffles his bishop between c4 and g8. No progress means draw. Remember this "rule".
