Well, remember that you're viewing it at 8 bits per component. That's 
256 levels, from 0 to 255. Try rendering to 48 bit PNG and viewing it in 
a program that does dithering. And I couldn't get accurate colors from 
your JPEG, so I'm not really sure what you're seeing. Also, make sure 
you're writing the data in the correct byte order, etc.

Aside from that, this group is for non-binary posts only. If you want to 
post an image, please post it in povray.binaries.images.
