Where on earth are people getting this idea to put all of their cools on one side of the stage or cat walk and all of the warm on the other? My college TD hangs everything this way on all of his plots. He also uses R60 as his "cool" which actually shifts the color temp of the set off, resulting in REPAINTING due to colors appearing to be different than what they are.
I was taught you hang you warms and cools all together on the left and right sides so you have even light with both warms and cools. Not one side of head cool other side of head warm.
