Okay, so, the "color" brown. It isn't on the visible light spectrum, so is it a color? (well I know that there can't be brown light...) Is it a mixture of wavelengths or what?

To amplify on the other answer, the reason the RGB system works is that our eye contains three types of color sensors, one peaking in the red, one in the green, and one in the blue. What we perceive as "colors" are what our brain assigns the combinations of signals from these three sources.
So those low percentages correspond to weak signals being given to those three types of sensors. If you have the same mixture but make it brighter, our eye will start to see it as a different color.
Same deal with neutral colors. Pure white is really bright R + G + B in equal amounts. But as you weaken the amounts but keep them equal, our brain sees it as grey.
