Light ist not added but it is multiplied on the surface.

light * surface = result
r,g,b * r,b,g = r*r, b*b, g*g

white light on white surface = white result
1,1,1 * 1,1,1 = 1,1,1 = white

white light on red surface = red result
1,1,1 * 1,0,0 = 1,0,0 = red

red light on white surface = red result
1,0,0 * 1,1,1 = 1,0,0 = red

red light on green surface = black
1,0,0 * 0,1,0 = 0,0,0 = black

yellow = red+green in rgb
yellow light on green surface = green
1,1,0 * 0,1,0 = 0,1,0 = green

i hope u c what i mean an it does help u a little.
