What Colour are Mirrors?

What colour are mirrors? Think.

Now you might say silver because most mirrors are made out materials that we associate to the colour silver like aluminium but obviously, when you put different coloured things in front of a mirror, it will show that colour. Just stating the obvious here.

But that just means that mirrors are reflecting white light, right? White light contains all colours after all.


However, if you put a mirror in front of a mirror, you would be able to see a tunnel of mirrors. The intensity of light starts to decrease and you eventually see a more greener colour at the end of the tunnel.

A lot of people say that mirrors are actually smart kinds of white, which is actually technically true.

A perfect mirror reflects back all the colours – white light, so the mirror is actually also white. Although in reality, real mirrors are not perfect, and their surface atoms give all reflections a very slight green tinge, since the atoms in the glass reflect back green light waves more strongly than any other colour.


Short post, but I thought it was quite interesting. 🙂
