    The mirror only reflects light and produce image of other objects.
    So what's the color of a mirror actually?

    Early mirrors were often little more than a sheet of polished metal, often silver or copper, for example the Aranmula kannadi. Most modern mirrors consist of a thin layer of aluminium deposited on a sheet of glass. This layer is called the Tain. They are back silvered, where the reflecting surface is viewed through the glass sheet; this makes the mirror durable, but lowers the image quality of the mirror due to extraneous reflections from the front surface of the glass (ordinary glass typically reflects around 4% of the light). This type of mirror reflects about 80% of the incident light. The "back side" of the mirror is often painted or coated in some way to completely seal the metal from corrosion.

    Mirrors for precision optical applications are more likely to have the reflective coating on the front surface of the mirror, to eliminate reflection from the glass. Metal films on the front surface are generally covered with a thin, transparent coating to protect them from corrosion. This is often made of silica. In some cases this coating may also enhance reflectivity.

    Mirrors designed for special applications, such as in lasers and other advanced optical devices, use a reflective optical coating composed of many layers of different dielectric materials. Such coatings can be designed to have extremely high reflectivity and are reasonably durable. Since they absorb very little of the incident light they can be used with high power lasers without absorbing the energy and being damaged.

    I'd say it's close to a shiny silver color. I look at the edges.

    So silver?

    Also cocks.

    If a word was misspelled in a dictionary how would you know it?

    A mirror reflects the whole spectrum of light.
    Therefore, it "has no colour".

    I could ask the same question for pure glass (ie. a window)

    Glass is green (or a blueish green). The color is quite apparent if you look through a sheet of glass from the side. Also, air is blue, that's why distant mountains are tinted blue. When you look at things up close there just isn't enough air between you and the object to notice the blue tint.

    Now that's something only a true scientist could've figured out!
