Unit array is tinted green for only one player. Please help

[Thunder_Lord]

What i need to do in my map is a fairly simple concept. I have a Unit Group array of size [14] called "colorarray". I need every unit in colorarray[1] to display a green tint that only player 1 can see, every unit in colorarray[2] to have a green tint that only player 2 can see, so on and so forth. then when a unit is no longer in to unit group its color for the specified player is reset to normal.
What would my triggers look like to accomplish this? and would i need any actors to do this? if so how would i set them up?
any help would be greatly greatly appreciated, this one kinda has me stumped /=.
