It turns blue.
Red litmus turn to blue in basic solutions.
When red litmus paper is added to soap solution, it will turn blue. This indicates that the soap solution is alkaline in nature, as alkaline substances turn red litmus blue. This is because soap solutions typically have a pH above 7.
Litmus paper turns blue in basic solution.
Blue litmus paper turns red when placed in bases. This is due to the presence of hydroxide ions in bases which react with the blue litmus paper, causing it to change color.
When a blue litmus paper is dipped in an acid, the paper will turn red. This color change indicates that the solution is acidic.
Dip the litmus paper into the solution you are testing. Hold it up in the air, holding the dry bit. Look at the bit you dipped. If the solution was an acid, red litmus will stay red, blue litmus will turn red. If the solution was an alkali, red litmus will turn blue, blue litmus will stay red. If the solution was neutral, red litmus will stay red, blue litmus will stay blue.
