It is red in colour because its 'soil' contians lost of iron. This has then oxidised, or rusted, causing the red appearence.
To the naked eye, it does look a reish colour and when seen through binoculars or a telescope, you can definatly see that it is red.

In the northern hemisphere, it is usually visible during the summer months.
