I built an M&M sorter that used a LEGO light sensor...
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=205439
It worked out pretty well, because I could just dispose of any evidence of mis-sorting.
As far as real results, I think it sorted about 75% correct.
I often read 3 colors (shades) with the light sensor. Black, Gray, & White.
