Litmus paper turn to red color.
The litmus papers are used for checking the acidic and basic nature of any substance. That's why drop of lemon juice, which is by nature acidic, turns blue litmus into red(as the property of acidic solution is to change the color of blue litmus to red). So soap solution which is by nature basic will turn red litmus into blue (as the property of basic solution is to change the color of red litmus to blue).
