In the second of my colour in nature series, I look at why desert sands can vary so much in colour; from white, yellow, red to black.
The colour of the desert sand comes in many colours and it will depend on the colour of the rock it weathered from.
White sand – is finely grounded up quartz.
Yellow sand – shows it is composed of feldspar and quartz.
Red sand – shows it is rich in iron.
Black sand – is from volcanic rocks rich in iron and titanium.
