Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under acidic conditions.
Zinc would have no effect on litmus paper. It is affected by solutions of acids and alkalis. I wonder if you have some acid and you are adding the zinc to that? If so, eventually, if there is enough zinc, the acid will be neutralized so instead of being pink with the acid, the litmus will go a purplish colour.
Blue litmus turns red in the presence of an acid. The opposite is correct in case of a base ie in presence of a base, red litmus turns blue in colour.
