Please make it a habit to post your system's info in every single new thread, as you did thankworthily in your very first post in here: "Debian 9 64x - LXDE".


As for your problem: the bash builtin echo needs the -e option. man bash:
Quote:
If the -e option is given, interpretation of the following backslash-escaped characters is enabled.
Same holds true for the external /bin/echo comand on linux systems. It does not necessarily on other systems.



Code:
echo "$red_start This text should be red $color_end"
\e[91m This text should be red \e[0m
echo -e "$red_start This text should be red $color_end"
 This text should be red
