Red travels the least distance, which is why the military uses it during night maneuvers, and all maps are designed to be read with a red filter.

you missed out on physics/any graphics imaging class. red, green, and blue are primary colors of light, you mix red and blue to get a secondary color, violet. same principle, just diff with light.
Are you kidding me? You mix blue and yellow to get green. Green is a secondary colour by that definition. I was asking for the definition that would make green a primary colour.

I don't see grape on that chart. Therefore it is incorrect.

Again, you're not getting the idea of distinguishing primary colors of pigments vs. primary colors of light.

ever heard of the RGB standard or RGB cables?
R=red G = green B = blue
any other color is a combination of those 3 in light

Others have already given example links that answer your question. But let me try to give you some explanation.
Paint:
[*]Paint absorbs light. Thus what reflects to your eyes is whatever the paint did not absorb. Thus a red paint absorbs all visible non-red light, and red light bounces back to your eyes. In a way, paint is the exact opposite of light. A blue paint absorbs all colors but blue. A green paint absorbs all colors except green.
[*]If you mix colors of paint, you can make something that appears black. The blue paint absorbs all but blue light. The red paint aborbs all but red light. The yellow paint aborbs all but the yellow light. Together, they absorb all light and you see nothing (black).
[*]The result is that every color you mix in, will reduce the light you see (they subtract as you mix).
Light:
[*]Light is the opposite of paint. If you see red light, you have only red colors, nothing else. If you see blue light, you see blue colors, nothing else.
[*]Light is additive. If you mix red light with green light, you see both the red and the green (which looks yellow). If you mix red, blue, and green light then you get all the colors and it looks white (a mixture of all colors).
[*]The result is that every light color you mix in, will increase the light you see (they add as you mix).
See the difference between paint and light? For paint, yellow is primary. For light, green is primary. That is why you have RGB monitors and RGB TVs. Red, Green, and Blue. Look at a TV very closely when it displays a white image. You'll see red bars, green bars, and blue bars.
