Adjusting Tint or Hue
This adjustment can be done using the same scene. Just like you did when adjusting color, try cranking your setting all the way up and down to get a feel for it. You should notice your picture going from a red hue, to a green hue at the farthest extreme.
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 it's RGB components. If you are fortunate enough to have this option, just follow the same principals we mentioned above for your calibrations.
