Again, the goal is simply to make your picture look natural. Generally, you want to remain somewhere in between the red and green hue. Keep experimenting within the middle range until you get the most consistent natural color. I used a scene that featured more than one face so that I could compare one to the other.

Some projectors will separate color and tint into its RGB components. If you are fortunate enough to have this option, just follow the same principles we mentioned above for your calibrations.
