Subject: When a beam of light falls on red cellophane (color filter film), why can we see it as red?

I have a science question about which I am very confused. I 
shine a beam of white light on a piece of red cellophane (color filter film)
in a dark room, and I can see that the piece of cellophane is red instead of a
black object by looking at the cellophane itself. I thought the red color filter
film was supposed to absorb all the colours of light except red and transmit
only the red light.  Then why do I still see the red colour of the color filter
film? Does the red color filter film also reflect some red light to my eyes as
well as transmit some red light?? Kindly enlighten me. Thank you and I hope to
hear from you soon.
