Fly screen for balcony door in which version?

I am looking for a fly screen door for my balcony door... There are ones with black plastic mesh, then ones with white, and also ones made of metal. What is worth buying? And what are the differences between black, white, and metal? I am interested in durability, as well as ventilation and visibility reduction (which basically doesn't matter for the door).

Fiberglass in gray, the view outside isok. Durable and lasts forever, our 8.5 kg tomcat (big not fat) often hangs on it, no damage whatsoever
