Ok, I was reading another thread about RAW and came across this word so I clicked the link to find out more. I came across Tan (blah, blah) :scratch: Since when is hue or RBG a cirlcle? Who came up with this and what was the reason? I'm curious now, I don't remember going over this in Physics 3, I may have slept through that class. I'm going to have to open that book up again.
