It is confusing to have say a "red" coded bag come it several different sizes. It would be easier to shop for the bags if each specific color coded bag edge is for a specific bag size. For an example, a "red" color coded bag is 8" x 6-1/2", and no other size. It should fit in both a "large single binder" and a "large double-binder". The other colors "yellow", "blue", "green", "gray", "brown", "black", etc., should each be for a unique refill bag size.
