why only red, green and blue are used to create other colors?
Ok, red and blue are on the egdes of visible radiation, but green? Its in the middle, why when i mix red and blue i get pink?

Visible light created by atoms has (nearly?)infinite ranges of waves varying from red to blue. Why same effect can be accomplished using only 3 frequencies RGB?

Why cant i use just blue and red? If i use 6 colors instead of 3, will i get more accurate image (will human eye see diffrence)?

RedGreenBlue because additive colorimetry.

MagentaCyanYellow is substractive colorimetry.


but i have a better question:

why do we have hands? why our skin is pink? why the life? why Red is Red? ... etc.

sometimes, it's simpler to don't ask anything and accept the fact as is.
color are like this, sounds are like that.

light is no created by atoms.
it is the visible manifestation of energy, wich can be induced by any energetized phenomenon, assuming there is a natural or artificial energy conversion system.

in theory, light is transported by photons.
in fact, photons are not matter, but energy channels, waves, or ropes, going at the speed of 300 000km/s,

we are in a universe were speeds are all lower than light speed, and there are universes were speeds are all higher than light speed.

then, red + blue = magenta.

in fact, for us, light is the eye, not the source. even when playing with pixels, only the eye can send a feedback to our brain and say it is ok.

welcome in ondulation world!!!
