Nice.
Don't forget to follow it with:-
$ . ~/.bashrc

I use:-
man() {
    env LESS_TERMCAP_mb=$'\E[01;31m' \
    LESS_TERMCAP_md=$'\E[01;38;5;74m' \
    LESS_TERMCAP_me=$'\E[0m' \
    LESS_TERMCAP_se=$'\E[0m' \
    LESS_TERMCAP_so=$'\E[38;5;246m' \
    LESS_TERMCAP_ue=$'\E[0m' \
    LESS_TERMCAP_us=$'\E[04;38;5;146m' \
    man "$@"
}

Default Debian .bashrc
# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval
"$(dircolors -b)"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    #alias grep='grep --color=auto'
    #alias fgrep='fgrep --color=auto'
    #alias egrep='egrep --color=auto'
