@Daniel: what if all of 26 balls are of green color? I think 48 should be the answer.

Best Case: You keep picking blue balls for three times and the 4th ball is surely of different colour. -Reason: You ran out of Blue Balls.
Worst Case: You keep picking green balls for 47 times. The 48th ball you pick is surely a different one. Reason: You ran out of green balls.

But understand the average case is not 26. The average case includes probability more than straight logic.

Depends on the color of the first ball you pick.
If you pick blue first then at max 4th ball will be of another color.
