I remember seeing something about this when I was a kid somewhere... I took my box of crayons and I made a little chart of what the colors looked like inverted by doing this over and over. I.e. Red = Green. Then I would draw pictures using the inverted colors just to do this to friends
I still have some of them to this day, simple drawings, American flag, barn in field etc...
That was back when color TVs were only just starting to not be a novelty
(Hey no computers, had to do something for entertainment!)
