The mirror has a crucial role in our everyday lives, whether we realize it or not. Have you ever wondered what would you do without a mirror when you need one? And have you ever wondered about the color of the mirror’s glass surface? It may appear without one. But if you draw a mirror, what would you color it? Probably light grey or blue. Which is fine, since movies and books portray it this way. But its actual color is green.
How could this be, you might ask. Well, the perfect mirror has a specular reflection, which means it reflects all light and image in a single direction equal to what it receives. Of course, the mirrors we usually use are far from perfect. They may show our reflection prolonged, a little bit shrank or even blurred. Most mirrors in our everyday life reflect green light more than they do other colors and that’s why our reflections often have a greenish tingle.
