  This is caused by the diffuse and ambient factors. To get a perfect
mirror you have to set them to 0, ie:

finish { reflection 1 ambient 0 diffuse 0 }

  The vector after the 'reflection' keyword (yes, it is a vector) is used
to specify the color of the mirror. '1' means just '<1,1,1>' ie. white, ie.
it reflects all color components. '<1,1,0>' would mean yellow window, ie.
it only reflects the red and green components but not the blue one.
  Funny things can be achieved by applying values greater than 1 to the
components...
