Please refer to the explanation below.

Explanation:

Acids turn methyl orange red and also litmus paper red.

To see that in a lab, take a few drops of diluted hydrochloric acid (HCl) using a pipette, and drop it into a solution of methyl orange (C_14H_14N_3NaO_3S). You should see the solution turn red.

With litmus paper, take a piece of blue litmus paper by hand and dip it into a solution of aqueous hydrochloric acid (HCl). You should see it turn red. With red litmus paper, this has no effect, and the colour stays red.
