5 stars because the part is cheap and good. All you need is for occasional shots there. Gold for exteriors (super for Außenportäts, the warm colors fit great to sunlight). Silver for flash photography in the studio (reflects most of the light of the flash and change color not). White serves the purpose and does not throw as much light back (Super for product photos) and Black can reduce the super reflections. So, out there to all amateur photographers access.
