Are you running your machine in 16-bit and taking screencaps? This may 
cause it. You should either run in 24- or 32-bit or take the actual output 
files from POV instead. The colouring takes a rapid plunge of 15 or so RGB 
units when I took a look in Paint Shop Pro which means it's getting 
16-bittized at some stage. (if 16-bittized is even a word :-) )

Sure hope this helps and BTW, when I first saw this image it looked like 
some kind of squid or octopus in water. Good job.
