Acid rain doesn't have a specific, visible color that we can easily identify with our naked eyes. Most of the time, acid rain appears yellowish, but it's often indistinguishable from regular rain. However, we can test for its acidity by letting a plain white cloth get wet in the rain. If the cloth shows signs of discoloration, it could indicate the presence of acid.
While acid rain may appear yellowish, it's important to remember that its color can vary depending on the pollutants present in the atmosphere and the intensity of the acidity.
