Uluru is famous for it's amazing range of colours. The colour changes have more to do with the effects the earth’s atmosphere has on the sun’s rays than with the geological make-up of the rock. When the sun is low in the sky the atmosphere acts as a giant prism, splitting the sun’s rays into a colour spectrum.

The light reaching Uluru (and also the nearby Kata Tjuta National Park) near sunrise and sunset is mainly from the RED end of the spectrum and its reflection from the rock gives the spectacular colour. The reddish-brown colour of the rocks and surrounding sands enhance these effects.
