ELI5: If mirrors are surfaces that don't absorb any color on the spectrum, what color are they ?

I have very little memories from my High School physics class but I remember that the color we see on an object is the light that reflects off its surface. All other colors on the spectrum being aborbed by the object.

Since a mirror reflects everything, then what can we say about it's color ?

Objects that are white also reflect everything, but they look white because the surface is rough and they scatter the light. Mirrors on the other hand (and things like smooth polished metal) maintain the angles of the incoming light, so you can see things reflected. So, mirrors don't really have a colour, but if you were to blend all the light together, they would probably look white/grey.
