All printers, both those human beings operating printing presses as well as those boxes on our desktops, use CYMK inks most of the time. And although we do not actually learn how to mix CYMK in primary school, it is something most of us arleady grasped by instinct. If you give a child a cyan, magenta and yellow marker, it will be able to draw a house with a red roof, green grass and blue clouds. Yes, children do draw blue clouds in a white sky. But they are able to grasp the essentials of CYMK.
I'm sorry but not only these children have no instict for RGB, neither do we. Just because NOBODY has ever been able or will ever be able to draw the colors cyan, yellow or magenta with just red, green and blue markers, or paint, or ink or whatever. Camera sensors, some scanners and all color CRT and TFT screens work with RGB. Screens mix light, not paint or ink, so I guess they have no other option than to use RGB. Cameras and scanners catch light of all wavelengths, they should be able to work just as well in CYMK as in RGB. The only scanner I've ever opened and analized used white light and red, green and blue filters in front of its sensor, sending the cyan, magenta, yellow and black informtion to the computer, which translated and stored it as RGB... By the way I believe that most scanners nowadays do have RGB sensors. not sure.
More and more software starts using hue, saturation and lightness. I know the theory behind it, I'm able to use it through trial and error, but I don't like it unless I want to create special effects.
Another option some programmers think we should like is to select parts of a picture and define them as "grass", "light skintone", "olive" and so on. Maybe some people can do miracles with it, I can't do anything that way.

For me CYMK rules.
