According to Doug, the "yellow color is not integral with the plastic, but is applied in much the same manner as the camouflage coating is applied to the standard Photons."

So there we have it. The glass-filled nylon housing is NOT yellow. The yellow coloring is applied to the housing much like paint is applied.

It's funny how one's mind thinks. I was thinking the camouflage coloring was "painted" on, but that the other colors were the true colors of the glass-filled nylon.
