Instead of seeing a plain output after a git command we can have the display in color.
like when we execute git status to view changed or new files we can view each segment in colored way:
or for when we execute git diff a_modified_file_name
it is better to view deleted lines in red (-) and added lines in green (+).
For the same add following segment into your git config file (.gitconfig) for me this file is at my home location i.e (~/.gitconfig)
[color]
ui = auto
[color "branch"]
current = cyan blue reverse
local = blue
remote = green
[color "diff"]
meta = blue
frag = magenta
old = red
new = green
[color "status"]
added = blue
changed = green
untracked = magenta
