This is what I use in my .profile file. Works like a charm because it allows me to see the current git branch as well as its state through the color.
If you want to modify it please note that it's important to escape color codes in order to avoid line feed problems in long lines.
# Setting GIT prompt
c_cyan=`tput setaf 6`
c_red=`tput setaf 1`
c_green=`tput setaf 2`
c_sgr0=`tput sgr0`
branch_color ()
{
if git rev-parse --git-dir >/dev/null 2>&1
then
color=""
if git diff --quiet 2>/dev/null >&2
then
color=${c_green}
else
color=${c_red}
fi

return 0

echo -n $color
}
parse_git_branch ()

gitver="["$(git branch 2>/dev/null| sed -n '/^\*/s/^\* //p')"]"
else
return 0

echo -e $gitver
}
