i don't have a problem with not getting the full color pics (i have learned to just deal with that)...i had a problem with the infrared not coming on at night and about 75% of my pics at night were just all black and i don't have any idea what caused this but after checking the camera, all the pics were fine.
Every now and then i get color pics but i never really expected to get many with my camera set-up (in the deep woods)...i would say however if you do want full color pics, you better set up the camera on field edge or a big opening in the woods..
just my 2 cents
