Why can red-orange made from transparent red and orange layers look different from directly mixed paint?
Answer and explanation
Correct answer: Layers create optical mixing while direct mixing combines pigment particles
The governing concept is the difference between optical mixing and physical pigment mixing. In transparent layers, light passes through one film, reflects from the surface, and passes through the layers again; the eye combines the coloured effects. Direct mixing blends pigment particles before application, changing absorption and scattering throughout one paint mass. Transparency, layer order, and surface colour can therefore alter the resulting red-orange. The other options contradict how transparent and mixed paints behave.
