Bash: ansi color when reading input from user

Question

When using read command to get user input like the following

read -p "[WARN] Text.. [Y/N]" choice

Is it possible to assign an ANSI color to the warning text, like in echo command?

WARN='\033[0;33m'
RESET='\e[0m'

echo -e "${WARN}Some warning message${RESET}"

Why not use `echo` for the prompt (you can use `-n` to not add the newline), and `read` to read the choice (without prompt)? — Some programmer dude, Sep 30 '18 at 08:12

reset='\e[0m'

echo -e -n "${warn}[WARN] Text.. [Y/N] ${reset}"

I suggest to add option `-n` to `echo` to avoid newline. – Cyrus Sep 30 '18 at 08:49
why mix `\033` and `\e`? (They're both acceptable, just styling preferences) – iBug Sep 30 '18 at 09:39
Just copied OP's code for that. – l0b0 Sep 30 '18 at 09:41
