Blue litmus paper turns redunder acidic conditions and redlitmus paper turns blue under basic (i.e. alkaline) conditions. The pigment in blue litmus reacts with H+ ions and changes chemically so the bonds are 'tuned' to reflect a longer wavelength of light toappear red to our eyes.Jul 24, 2014

Explanation:

when an acid is added to an indicator solution, the acid donates protons to the water molecules. This increases the concentration of H3O+ ions in the solution. The H3O+ ions donate protons to the indicator molecules causing the indicator to change color toward red.
