Actually, you're both right! F-ONE is correct if you are discussing PIGMENT. THEORETICALLY, if you mix the primary colors in equal parts, you get black. (Actually you get a dark muddy brown...try it sometime with oil or acrylic art paints!) HRP is correct when speaking of LIGHT. Black is the absence of all light, or at least all "visible" light. So, to put it all together...If F-ONE puts equal parts of each primary color on his hot rod, then the pigment "absorbs " all the light and no color is reflected for HRP to see.
