You can't, as it won't reflect light beams.....

but the best you can do is
texture{finish{reflection 1}}

  There's something I haven't understood about the reflection.
  Doesn't 'reflection 1' mean "reflect ALL the light"?. If so, why if I
give the mirror, for example, a red color, the reflection is reddish? It isn't
reflecting ALL the light, but modifying it.
  If you want a true colored mirror, you should (as the documentation says)
put that color in the _reflection_ statement, not in the color statement of
the mirror (for example a red mirror should have 'reflection <1,0,0>').
  I have understood that when you put a 'reflection 1' in the finish block
of the object, then the color of the object becomes obsolete, since it
reflects absolutely all the light and none of its own color. But it seems
to work differently. Could anyone explain me how this really works?

The reddish color comes from the diffuse light and the ambient light. 
As they are still red, and added to the reflected light.

If you add finish{reflection 1 diffuse 0 ambient 0} you'll get a white
mirror, even if your sphere is red.

A penny for your thoughts.
Mine are more expensive.

If you mean something that's completely refectlive with no diffuse or
ambient light it would be this (at least this is what I use any way):

texture {
pigment {
color rgb <1,1,1>
}
finish {
diffuse 0
ambient 0
reflection 1
phong 1
phong_size 100
}
}
