Therefore, the label mixed must be in either a red or a blue box.
Just pick a ball from the mixed box, then.

If you pick blue:
–>  mixed should be blue
–>  red should be mixed (it was misplaced; can’t be red)
–>  blue should be red

If you pick red:
–>  mixed should be red
–>  blue should be mixed (it was misplaced; can’t be blue)
–>  red should be blue

Start with the box marked as mixture.  You know this box must contain only blue or only red, otherwise the label would be correct. 

Pick the ball.  If red, then it the red only box.  If blue, it’s the blue only box.  Place the correct lable on it. 

Now one of the boxes has a only label and one box has no label.  You know the one with the missing label can’t be the mixed box because that would mean the one with the only (blue or red) label would be correctly labeled.  So remove the box’s only (blue or red) label on the unmarked box.

Take the remaining mixed lable and place it on the box that now has no label. 

You’ve now changed every label and that was required because “ALL WERE MISLABELED”. 

Did I get it right?
