Adding color to a shell script?


Is it possible to add color to a shell script so that when a user runs the script, the text is in color

eg:

#!/usr/bin/sh
# game1.sh: Asks user to guess a number 5 times
# Answer is 12 and max tries is 5
count=0 ; counter=0
while ((count < 6 )) ; do
echo "Enjoy my first game!"
echo "Go ahead and guess a number, or hit ctrl c to exit:" 1>&2
read number
if [ $number -eq 8 ] ; then
echo "Congradulations, you guessed the number and get a cookie" ; exit
else
let counter=1
let count=1

echo "Sorry that was incorrect, you have 4 guesses left. Guess another number or press ctrl c to exit:" 1>&2
read number
if [$number -eq 8] ; then
echo "Congradulations, you guessed the number and get a cookie" ; exit
else
let count=2
let counter=2

echo "Sorry that was incorrect, you have 3 guesses left. Guess another number or press ctrl c to exit:" 1>&2
read number
if [$number -eq 8] ; then
echo "Congradulations, you guessed the number and get a cookie" ; exit
else
let count=3
let counter=3

echo "Sorry that was incorrect, you have 2 guesses left. Guess another number or press ctrl c to exit:" 1>&2
if $number -eq 8] ; then
echo "Congradulations, you guessed the number and get a cookie" ; exit
else
let count=4
let counter=4

echo "Sorry that was incorrect, you have 1 guess left. Guess another number or press ctrl c to exit:" 1>&2
if $number -eq 8] ; then
echo "Congradulations, you guessed the number and get a cookie" ; exit
else
let count=5
let counter=5
echo "Thanks for playing." 1>&2
if [ $count -eq $counter ] ; then
break
echo "Play again soon!"

Google around for "bash ansi color codes", for example:

This link discusses using colours in a script. There is a script somewhere which generates a table of the ANSI colours but I can't find it right now, I'll have a look.

EDIT:
I found the script I mentioned, it's quite useful for knowing which code corresponds to which colour.
Code:
#!/bin/bash
#
#   This file echoes a bunch of color codes to the 
#   terminal to demonstrate what's available.  Each 
#   line is the color code of one forground color,
#   out of 17 (default + 16 escapes), followed by a 
#   test use of that color on all nine background 
#   colors (default + 8 escapes).
#

T='gYw'   # The test text

echo -e "\n                 40m     41m     42m     43m\
     44m     45m     46m     47m";

for FGs in '    m' '   1m' '  30m' '1;30m' '  31m' '1;31m' '  32m' \
           '1;32m' '  33m' '1;33m' '  34m' '1;34m' '  35m' '1;35m' \
           '  36m' '1;36m' '  37m' '1;37m';
  do FG=${FGs// /}
  echo -en " $FGs \033[$FG  $T  "
  for BG in 40m 41m 42m 43m 44m 45m 46m 47m;
    do echo -en "$EINS \033[$FG\033[$BG  $T  \033[0m";
  done
  echo;
done
echo
