Display ANSI colors with their color-code.

function colormap() {
    range_start=${1:-1}
    range_end=${2:-255}

    for i in $(seq $range_start $range_end); do
        echo -en "\e[48;5;${i}m  ${(l:3::0:)i}  \e[0m "
        [[ $((i % 10)) -eq 0 ]] && echo
    done
    return 0
}

The colormap function will print the ANSI colors with codes in your terminal.

$ colormap           # (000 - 255)
