moving rock if it is that much of a pain.
generally i glue corals on pieces of rubble or fist sized rocks while they grow or encrust. during that period i experiment going higher or lower. the coral will react during this experimentation as i get it where i want the colors to be. usually it takes 6 months or more for it to outgrow the rubble. (plenty of time to find the sweet spot)
you can also spike the whites during certain times as well if you have quadrants that can be lit differently.
placing all corals in a tank and expecting them all to color perfectly in random areas is luck of the draw. however you can get it to where 75% of them are optimal in their current position, the other 25% you will have to "rework" to get to your liking.
or just leave it how it is
