Technically the litmus paper should stay blue, but depending on where you live and how your water is treated it can become pink or red. If you use distilled water then it will stay a neutral color but with traces of minerals and chlorine to make tap water safer to drink, the water either becomes slightly acidic or basic. It really just depends on where you live.
