Identifying Specific Oven Trays

christyxo2

Hey. I know it's not quite the place to ask but maybe someone will have a suggestion. In this house we have a vegetarian, someone who doesn't eat pork, and someone who eats all meat.
I have just replaced our baking trays with new ones but I'd like to find a way to mark them out for specific uses... much like restaurants where they use green utensils for vegetables only. It really is only to eliminate cross contamination.
Is there someway that I can clearly mark a baking tray so it's use is obvious? Is there a safe paint/varnish that can withstand an oven and subsequent washing? Any ideas?

Just stamp a pattern or markings onto the trays with a screwdriver or similar.

Or encourage the non-pork / meat eaters to eat pot noodles all the time.
