   When light hits paint, part of the light reflects, and part penetrates into the   
   body of the paint and interacts with pigment particles.   
   The 'reflects' part is white light, and the interacting light is colored by   
   the pigment.   
      
   So, colors of many objects become exceptionally vivid when viewed through   
   a polarizing system (depending on the incident light source and aim   
   considerations   
   of the polarizing axis).  Take a few snapshots with a polarizer, of random   
   items (fabric, paint, glazed   
   pottery) that have part-transparent composition.   Even oil-finished wood   
   grain just seems to   
   pop with the right polarizer setting.
