let's add a comment above this to indicate what these tput are for, or add
readonly variables for them?

You can also use the following escape sequences:

readonly RED_COLOR="^[[31m"  # Note: ^[ is the escape char
readonly NO_COLOR="^[[0m"
echo -e "${RED_COLOR}message${NO_COLOR}"

Added comment- benefit (as I understand) of using tput is that it will avoid
escape chars if they'll cause an error in the current environment.
