We are loving this clever, interactive billboard by Koleston Naturals, a hair company that specializes in hair dye made of natural ingredients. What better way to illustrate natural characteristics than by using nature itself? Obviously, the location was key for it to work, and this billboard actually appeared on the coast of the beautiful country of Lebanon. You’ll notice that the colors of the hair change with the sun throughout the day to reflect the variety of colors Koleston Naturals has to offer. Now that’s thinking outside the box.
