In the other colors modes like Cinema Mode which represents the second image in the gallery, you will notice that the colors are pretty innacurate, however, Cinema Mode is for exactly what it says it is. So you might find this mode to excellent depending on the movie content you plan to show. The color wheel really isn't the best judge of picture quality when it comes to the Cinema Mode.
PC Mode which is image 3 in the gallery was pretty good, but yellow has sort of a greenish look to it. Personally would probably avoid this mode. Photo Mode represents the last image in the gallery and its colors were a bit washed out. The black would be a good example of this. Ultimate I would recommend running this projector in Bright Mode all the time and dropping the white intensity to 5. Is it necessary to drop the white intensity? Not at all, but if you want just a slightly better image, it helps.
