The simple explaination of why yellow monochromatic light looks the same as equal combinations of green and red light is that the color receptor systems in the eye (the cones) have sensitivity curves which trail off (I remember them as being roughly gaussian). A signal halfway between the two peaks excites the two receptors equally, as do two signals right on each peak.
