Prety easy. Take a look at the optics.pov smple scene.

The principle is to have a mirror that reflact a single colour or two 
and transmit the part that is not reflected.

This is taken verbatim from the mentioned scene:
#declare RedMirrorTex =
texture {
     pigment {color rgb < 0, 1, 1> filter 1}
     finish {ambient 0 diffuse 0 reflection Red}
}

The pigment let pass the blue and green, while the reflection part 
reflect the red part.
