What color is a Mirror?

Hoping that you might have seen the answer yourself without realizing, it will not be very hard to explain that a mirror is not colorless. At first, you might think that a mirror is a silverish-grey, because in catalogs and illustrations this is the color used to display a Mirror. You might think that colorless is the right answer because this is the color reflected. But since we live in a world where nothing is perfect a perfect mirror doesn’t actually exist, mirrors do have a color. A mirror should reflect all colors equally but a shade of Green is reflected better. This is essentially, why if you look at a mirror tunnel, such as the one pictured above you will see that it becomes greener and darker. Now you know!
