Hiii
In order to change the colour of litmus paper, you’d need to have an aqueous solution of whatever compound you wanted to test or wet the paper so that the gas can dissolve. Dry HCl obviously isn’t in solution and the paper itself is dry, so the paper won’t change from its neutral purple colour - HCl only acts as an acid when in aqueous solution.
Dry Hcl gas does not contain any hydrogen ions in it, so it does notshow acidic behaviour. Dry HClgas does not change the colour of dry litmus paper as it has nohydrogen ions [H+(aq) ions] in it.
Hope it helps u ^_^

We know that the colour of litmus paper is changed by H + ions because of acid.
Dry HCL it does not dissociate to give H+ ions.
Acids dissociate to give ions only in the aqueous solution.
In this HCL is not in aqueous form nor litmus paper is wet, so the colour of litmus paper does not change.
