I am using mate terminal.

I found another way which is easier to use and tput is part of the ncurses package and is supplied with most Linux distributions.

Code:

FILE="/usr/share/sounds/My_Sounds/Short_doorbell.wav"

if [ -f "$FILE" ];
then
     tput setaf 2; echo "File $FILE does exist."
else
     tput setaf 1; echo "File $FILE does NOT exist."
     
fi
tput sgr0    # Reset text format to the terminal's default


#Num  Colour    #define         R G B

#0    black     COLOR_BLACK     0,0,0
#1    red       COLOR_RED       1,0,0
#2    green     COLOR_GREEN     0,1,0
#3    yellow    COLOR_YELLOW    1,1,0
#4    blue      COLOR_BLUE      0,0,1
#5    magenta   COLOR_MAGENTA   1,0,1
#6    cyan      COLOR_CYAN      0,1,1
