GUEST,keith A o Hertford BS: Why are rain clouds Black (29) RE: BS: Why are rain clouds Black 24 May 10


Rain clouds look white from above.
They only look black from below because they are so dense.
Why things look any colour is to do with how they reflect.
Snow and clouds look white because they reflect and scatter all colours equally.
White is not a real colour but how we perceive a mixture of all colours of light.
We are even fooled into thinking we see all colours and white on TV when really only 3 colours are present.
