I run my actinic for 14 hours/ day and my MH 12 hours per day.
I did the 4 to 6 hours with MH per day when I was batteling heat issues in the summer and while the corals stayed alive they did lose a little color. so the info Doug and myself had read about the saturation point in corals being reached after 4 to 6 hours might have been mearly for them to live.
I now believe for real nice color you need more than this basic requirment.
