Where to acquire the "colors" command?

[fakedeltatime]

In the readme there's displayed a command that nicely shows the current theme colors. Is this merely a fictional command, or does it exist? Most I have seen in different Linux distribution repositories don't have as nice of a style.

ohh is and alias

colors () {
    # echo ""
    #black
    echo -e "\e[0;30m ███ *** AaBbCs ---  ███ \\e[0m   ---> Color 01 0;30m"
    #red
    echo -e "\e[0;31m ███ *** AaBbCs ---  ███ \\e[0m   ---> Color 02 0;31m"
    #green
    echo -e "\e[0;32m ███ *** AaBbCs ---  ███ \\e[0m   ---> Color 03 0;32m"
    #yellow
    echo -e "\e[0;33m ███ *** AaBbCs ---  ███ \\e[0m   ---> Color 04 0;33m"
    #blue
    echo -e "\e[0;34m ███ *** AaBbCs ---  ███ \\e[0m   ---> Color 05 0;34m"

    echo -e "\e[1;37m ███ *** AaBbCs ---  ███ \\e[0m   ---> Color 16 1;37m"
    echo ""
    echo -e "\e[0;30m█████\\e[0m\e[0;31m█████\\e[0m\e[0;32m█████\\e[0m\e[0;33m█████\\e[0m\e[0;34m█████\\e[0m\e[0;35m█████\\e[0m\e[0;36m█████\\e[0m\e[0;37m█████\\e[0m"

}

also i got this one:

colors256 () {
    for (( i = 0; i < 256; i++ )); do
        echo -e "\e[38;5;${i}m ████ Color: ${i}  ······· use: echo -e \"\\\e[38;5;${i}m TEXT\" \n"
    done
}
