Litmus paper is neutral and has a PH of 7 o adding an alkali will turn it purple and adding an acid will turn it red-pink.
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.

Red litmus paper remains red when a neutral solution is added. This is because neutral solutions do not affect the color of red litmus paper.
Blue litmus paper turns red when grape juice is added, indicating that the solution is acidic.
Hydrochloric acid is an acidic solution, so when litmus powder is added to it, the litmus powder would most likely turn red. This is because litmus paper turns red in acidic solutions and blue in basic solutions.

The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless
