Why do clouds turn pink?

Firstly, sunlight scattered by the cloud towards our eyes is scattered again by air molecules. Shorter wavelength blues and greens are scattered out of the direct line of sight more than red, causing the cloud's light to be reddened. The reddening of the sun at sunset is the same effect.

Why do clouds turn grey?

When clouds are thin, they let a large portion of the light through and appear white. But like any objects that transmit light, the thicker they are, the less light makes it through.
