Discrimination of dimension for each box are as follows:-
- One set of red: one dimension variation - width.
- One set of yellow: two dimension variation - height and width.
- One set of green: two dimension variation inverse to that of the yellow set - height and width.
- One set of blue: one dimension variation - height.
