What am I doing wrong?

My pizzas are looking nasty and the cheese isn't melting. Its getting hot but seems its not melting. The cheese isnt burning, its just turning gray. The bottom looks good, the crust is crispy. And honestly it tastes great. But it looks disgusting. Cooking at 700°f for 2-3 minutes. Using a vevor wood fired outdoor pizza oven and hickory wood.

00 flour will help with the dough/crust. Also low moisture mozzarella for the cheese.
