A two tone storage bin for a product includes a body having a bottom wall and two opposed side walls, a front end wall of a first color and a rear end wall of a second color connected thereto. The two end walls have a height lower than a height of the side walls to form a front bin opening and a rear bin opening. A divider wall is positioned midway of the body to form a front hopper and a rear hopper, each of which is filled with a product. When the front hopper is empty and product in the bin needs replenishing, the bin is turned around so that the rear end wall of the second color faces outwardly to provide a visual indicator that replenishment of the product in the bin is needed while there is still product left in the rear hopper.
