From my understanding, when white light hits a surface, all of the frequencies within the white light are absorbed except one, which is reflected, and that is the color of the object. For instance, a blue plastic appears blue because it absorbs all frequencies except that of blue. Why then, can certain materials, colored plastics in particular, reflect images in color. Images reflected in plastic are not as vivid as a mirror, but they are in color nonetheless. Why if a material can show a reflection is it not just a different color? For instance, I can see by looking at the back of my phone case, blue plastic, that the shirt I'm wearing is red. If the case can reflect red, why isn't the case itself just red? What properties of material or light allow reflections to be seen over other colors?
