vim

vim is a highly configurable text editor for efficiently creating and changing any kind of text. It is included as "vi" with most UNIX systems and with Apple OS X.

In my case, I am not to see the remark easily, so I changed its environment by creating ~/.vimrc like below

syntax on
colorscheme slate
set encoding=utf-8

If you want to set above globally, you need to add above two lines at the end of /etc/vimrc

So eventually you will be able to see a little bit different colors like below:

If you want other color schemes installed, you can try among below:

blue.vim
darkblue.vim
default.vim
delek.vim
desert.vim
elflord.vim
evening.vim
koehler.vim
morning.vim
murphy.vim
pablo.vim
peachpuff.vim
ron.vim
shine.vim
slate.vim
torte.vim
zellner.vim
