The secondary colour doesn't do any keying or any converting to Hue,Sat,Value -
it separates RGB, CMY and whats left through subtraction and max's, changes the
colour then adds them back, so it is very clean.
I tested Ron's Hue against PS and they create similar artifacts with a
colourwheel, so its probably similar maths behind.
