Rainbows from acid rain

Rain causes rainbow.... rainbows are beautiful... they give you a sense of hope and peace amidst gloomy cloudy sky and thundering downpour.... what makes them beautiful? is it the light? is it the water? or is it the sky in which light is scattered? or is it just the rainbow itself.. :)

Rainwater is supposed to be the purest form of water.. but due to pollution, they are far from purity nowadays.. acid rains are common in big cities...

If a rainbow is formed by acid rain, would the rainbow still look beautiful? Or because the rain is due to pollution, would the colors be different? would the rainbow be even visible due to the pollution in the sky??!!

When there is light and are water drops, there'll always be rainbows... They say, beauty lies in the eyes of the beholder.. But can the eyes see the rainbow to appreciate it?
