Perhaps some red dye?
But hydrochloric acid turns blue litmus paper red.
Hydrochloric acid will keep litmus red - it needs alkali to turn it blue
The red litmus paper will turn blue when dipped in hydrochloric acid. This is because hydrochloric acid is acidic, and acids turn blue litmus paper red.
hydrochloric acid usually has pH 1 which turns litmus Red
Litmus paper would turn red in the presence of hydrochloric acid, indicating acidity.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.

HCl(Hydrochloric acid) makes NaCl when it reacts with NaOH.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Red
Hydrochloric acid is an acid, so it reacts with methyl orange, which is a pH indicator. When added to hydrochloric acid, methyl orange turns red due to the low pH of the acid. This color change indicates the presence of an acidic solution.
Universal indicator will turn red or pink in dilute hydrochloric acid.
Litmus paper will turn red in dilute hydrochloric acid, indicating that the solution is acidic.
