VIM colour scheme

Fire up vim, then type:
:colorscheme [SPACE] [TAB]

By hitting tab each time, you can see the different schemes available.

Or you can type:
:colorscheme [SPACE] [CTRL + d]

to list all the schemes.

Or instead of typing :colorscheme, you can use:
:colo

Finally to change the default colour scheme and make it permanent, edit:
~/.vimrc

And add the line:
colorscheme [COLOUR SCHEME]

For example:
colorscheme desert

Save the file and you're good to go!
