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.
