Политкорректная цветокоррекция

Quite a few years ago, I was having trouble with blacks becoming a tad green when turning saturation down all the way. I was working night shift at the time, so direct communication with the engineer was difficult. I decided to come into work early one day to demonstrate the problem in person. As I marched into the control room with engineer in tow, I said something like, "no work is going to get done around here until these blacks are taken care of...." All became very, very quiet as I opened the door to a room full of producers working on a rap music video.
