It helped me to finally achieve an accurate Spectraflame shader.

"Spectraflame" is automotive candy paint sprayed directly on top of zinc plated toy cars and contains both standard as well as flourescent pigments, so there is not only "sparkle" due to imperfections in the plating, but also a noticeable color shift.

Cool - nice Hotwheels shader
