It is??? I thought it was mostly blue since it is almost 90% covered with water.
Unless you are talking about Dirt........it is brown. Not sure why. Ask a geologist.

It took a while to figure out what earth is made of, but invariably it is a metal mixed with an halide. For example, metallic iron and oxygen combine to form iron oxide (rust) which is brown.
This also explains where we get metals from - they are mined from the earth and stripped of their oxides to get the metallic compounds.
Not all metal/oxide combinations form brown compounds, for this reason not all earth is brown. In Georgia, the colour of the earth is a famous red color.

Earth is the rock dust that has been eroded from rock over millions of years. If that rock had a lot of iron in it, which most did, the iron oxide (rust) is perceived by our eyes as brown, or reddish-brown. Where there were different elements in the rock, such as sulpher, the rock as it wears down is more yellow in color. Just depends on the main coloring mineral that was in the rock to begin with.

earth is brown because it absorbs all the colours from the rays of light and reflect only the brown colour

One of the most stable elements is iron. Iron is very reacitve with oxigen, particularly if also water or moisture is present. So wherever occurs iron (and in traces it occurs almost everywhere) you can see the reddish-brown of ironoxide.
Also manganese-oxide is brownish and in traces also isn't really rare.

Earth is made up of dust, and the dust is dark color of black. However the sunlight lit up the sky with light color, bring out the light out of dark which is brown, because it is dust true color.

If you take every color of water paint and mix it together, you get brown. Same with all the particles mixed up together.

Most of it is Blue because 90% is water.and its brown because of the land.
