How to get the list of all installed color schemes in Vim?
You can see the list of color schemes under /usr/share/vim/vimNN/colors (with NN being the version, e.g. vim74 for vim 7.4).
This is explained here.
On the linux servers I use via ssh, TAB prints ^I and CTRLd prints ^D.
If you are willing to install a plugin, I recommend https://github.com/vim-scripts/CycleColor.
to cycle through all installed colorschemes. Nice way to easily choose a colorscheme.
Just for convenient reference as I see that there are a lot of people searching for this topic and are too laz... sorry, busy, to check for themselves (including me). Here is a list of the default set of colour schemes for Vim 7.4:
blue.vim
darkblue.vim,
delek.vim
desert.vim
elflord.vim
evening.vim
industry.vim
koehler.vim
morning.vim
murphy.vim
pablo.vim
peachpuff.vim
ron.vim
shine.vim
slate.vim
torte.vim
zellner.vim
Type
:colorscheme then Space followed by TAB.
or as Peter said,
:colorscheme then Space followed by CTRLd
The short version of the command is :colo so you can use it in the two previous commands, instead of using the "long form".
If you want to find and preview more themes, there are various websites like Vim colors
