What Hue Does a Mirror Possess?

Did you know that mirrors have a color? Although it is light, it is still a color!

Mirrors are everywhere, from your bathroom to the side of your car, and they only have one job: reflecting.

Whether it’s reflecting for pure vanity or to ensure that you’ve wiped off every bit of powdered sugar from your face, or to see that reckless driver racing past you while you’re changing lanes on the highway, they’re a lifesaver and yet so simple.

Today, we will answer a question that you have probably never pondered, but once you hear it, you won’t be able to stop until you’ve read this article…

What is the color of a mirror?

The mirror affixed to the front of your wardrobe is nothing more than a substrate of soda-lime silica glass with a silver backing.

To put it simply, it is a silvery sheet of soda-lime glass.

The true color of this soda-lime mixture is green, a faint green, but green nevertheless.

Your silvery wonder is green, a faint green I grant you, but green nonetheless.

How do we know this?

In Grenada, Spain, back in 2004, two researchers, Raymond L. Lee, Jr. and Javier Hernández-Andrés, conducted an experiment in one of the Science Museums most popular attractions; the mirror tunnels.

The mirror tunnels is a contraption that contains two mirrors facing each other with two eye holes cut out for the curious visitor to peer into.

The researchers discovered that when the mirrors’ reflections are bounced back and forth over 50 times, the green wavelength becomes the predominant wavelength we see.

As a result, we can begin to see the greenish truth beneath, and for all us science nerds, the green wavelength is 552 nanometers or, more vaguely, anywhere between 495 and 570 nanometers.

Why do we see the mirror as purely reflective of what surrounds it?

I’m sure I’ve heard a mirror is actually white?” Well, this is where the fun part comes in; the science behind the reflections is that white does indeed make some sense because white reflects all light, and black absorbs all light.

However, when it comes to white, you’re probably wondering why the mug on your desk or the shirt on your back doesn’t reflect the tapestry of colors around you?

The answer is simple: white reflects all colors in all different directions, in a process known as a diffuse reflection, whereas mirrors reflect colors straight back in the direction they’re facing as a concentrated source, which is known as a specular reflection.

This allows us to see the object as it is before the reflection.

For instance, if you hold up a blue square with the letter “B” on it in front of a white background, it won’t reflect anything visible. But if you hold that same blue square in front of a mirror, you’ll see nothing less than the exact square with the letter “B” in reverse being reflected back.

Summing Up

Thus, we have concluded the answer to a question that may not have even crossed your mind. Those moments of distraction are now a thing of the past.

The modest mirror is simply a rectangular block of soda-lime with a glossy surface.

However, it is undeniable that I am eager to visit Grenada and witness the mirror tunnel firsthand.


1. What color is a mirror?

A mirror doesn’t have a color of its own. It reflects light and the color of the reflected image depends on the color of the objects placed in front of it. When light hits a mirror, it bounces off and the reflection shows the color of the object in front of it. So, a mirror can reflect any color that is placed in front of it.

2. Why do some mirrors have a greenish tint?

Some mirrors have a greenish tint because they are made using a glass that contains iron. The iron content in the glass gives it a greenish tint. This type of mirror is called a “green mirror”. The amount of iron in the glass affects the amount of green tint in the mirror.

3. Can mirrors be made in different colors?

Yes, mirrors can be made in different colors by adding a thin layer of metal or other material to the reflective surface. This process is called “coating”. For example, a mirror with a gold coating will appear to have a golden color. However, these types of mirrors are not commonly used for everyday purposes.

4. Why do some mirrors make objects look distorted?

Some mirrors make objects look distorted because of the way they are curved. Concave mirrors, which curve inward, can make objects appear smaller or larger than they actually are. Convex mirrors, which curve outward, can make objects appear farther away or smaller than they actually are. The degree of distortion depends on the degree of curvature.

5. Can mirrors reflect all types of light?

Yes, mirrors can reflect all types of light, including visible light, ultraviolet light, and infrared light. However, the amount of reflection may vary depending on the type of light. For example, some mirrors may reflect more ultraviolet light than visible light.

6. How are mirrors made?

Mirrors are made by coating a sheet of glass with a thin layer of metal, such as aluminum, silver, or gold. The glass is first cleaned and polished to ensure a smooth surface. Then, the metal is deposited onto the glass using a process called “vacuum deposition”. This creates a reflective surface that can be used as a mirror.

7. What are some common uses for mirrors?

Mirrors have many common uses, such as in bathrooms, bedrooms, and dressing rooms for personal grooming. They are also used in cars for rear-view and side-view mirrors, and in telescopes and microscopes for reflecting light. Mirrors are also used in art and design for their reflective properties.
