The simplest way to achieve this is to implement the xterm esc and
script your shell prompt so it prints the esc followed by your regular
prompt.

Not tested:

settermbg() {
    echo -ne "\e]49;$1\a"
}

dirbg() {
    case $PWD in
        /mydir*) settermbg 1 ;;
        /foobar*) settermbg 42 ;;
        *) settermbg 0 ;;
    esac
}

# the \$(cmd) in PS1 is probably bash-only
# maybe PROMPT_COMMAND is more portable
PS1="\$(dirbg)\u \w $"
