Maybe you’d like to replace "Intensty" with "Intensity". Thank you for this nice gist

@call-nick Good catch! I updated that.

In case anyone wonders what the names mean:

printf "\e[0;30mBlack\n"
printf "\e[0;31mRed\n"
printf "\e[0;32mGreen\n"
printf "\e[0;33mYellow\n"
printf "\e[0;34mBlue\n"
printf "\e[0;35mPurple\n"
printf "\e[0;36mCyan\n"
printf "\e[0;37mWhite\n"

printf "\e[1;30mbold Black\n"
printf "\e[1;31mbold Red\n"
printf "\e[1;32mbold Green\n"
printf "\e[1;33mbold Yellow\n"
printf "\e[1;34mbold Blue\n"
printf "\e[1;35mbold Purple\n"
printf "\e[1;36mbold Cyan\n"
printf "\e[1;37mbold White\n"

printf "\e[0;90mhigh intensity Black\n"
printf "\e[0;91mhigh intensity Red\n"
printf "\e[0;92mhigh intensity Green\n"
printf "\e[0;93mhigh intensity Yellow\n"
printf "\e[0;94mhigh intensity Blue\n"
printf "\e[0;95mhigh intensity Purple\n"
printf "\e[0;96mhigh intensity Cyan\n"
printf "\e[0;97mhigh intensity White\n"

And it looks like
