It is a indicator. It indicates colors according to acidity.
if you are working with a strong acid the lithmus paper will turn red.

lithmus paper
Acids turn litmus blue. Litmus paper is a pH indicator that turns red in the presence of acids and blue in the presence of bases.

Acids can turn different colors in indicators like litmus paper. They turn red in litmus paper, yellow in phenolphthalein, and orange in methyl orange.
Litmus paper can turn red in acidic solutions and blue in basic solutions. These color changes occur due to the pH-sensitive dyes in the paper reacting with the hydrogen or hydroxide ions present in the solution.
Litmus is a mixture, not a single compound.
Acid turns it in red, while base will turn it blue.
Red color in acidic solutions and blue color in basic solutions.
When moist blue litmus paper turns red, it indicates the presence of an acidic gas such as carbon dioxide (CO2) or sulfur dioxide (SO2). This change in color is due to the acidification of the blue litmus paper by the acidic gas.
