Im probably missing something, but:

I have a red reflecting sphere and a white light source and a white 
plane and many photons. Should the light reflecting from the sphere 
(showing on the plane) be red, not white? Now it is white. I'd think 
that the red sphere should absorb all the other components but red. Or 
should it? So, is my thinking flawed or is this a feature/bug in 
POV-Ray's photon mapping? Most likely I'm missing something very obvious 
here so please correct me.

See the next scene:

camera {
     location  <1, 3, -2>
     look_at   <0, 0,  0>  }

light_source{<5,10,-5> rgb 1}

global_settings {photons { count 100000}}

plane {y,0 pigment {rgb 1} }

cylinder{0,y,1
     pigment {rgb x}
     finish {reflection 1}
     photons {target reflection on}
}
