The "right" way is to output the character sequence needed based on terminal type... thus you get the sequence from termcap/terminfo. Most systems will now use terminfo... you can use tput to output a capability string. You can use infocmp (if installed) to view the current terminfo database for your terminal type.

As far as "red" goes, that could vary. Often times you use the "tput setaf #" command to output a color by NUMBER. Red is often times color 1, so
tput setaf 1 would change the foreground to red. In a script you would capture the string to use in output (at least that's what I'd do). So if "tput setaf 1" means red foreground, and "tput sgr0" means reset graphics/charsets/color to nothing... then:

r=`tput setaf 1`
N=`tput sgr0`

echo "The following ${r}WORD${N} should be in red."

Or

printf "The following %sWORD%s should be in red.\n" $r $N

Because terminal type can vary, even from one terminal client to another, it's difficult to depend on things like color (especially color).

tput

TPUT(1) 						    BSD General Commands Manual 						   TPUT(1)

NAME

     tput, clear -- terminal capability interface

SYNOPSIS

     tput [-T term] attribute ...
     clear

DESCRIPTION

     The tput utility makes terminal-dependent information available to users or shell applications.  When invoked as the clear utility, the
     screen will be cleared as if
	   tput clear
     had been executed.  The options to tput are as follows:

     -T      The terminal name as specified in the termcap(5) database, for example, ``vt100'' or ``xterm''.  If not specified, tput retrieves the
	     ``TERM'' variable from the environment.

     The tput utility outputs a string for each attribute that is of type string; a number for each of type integer.  Otherwise, tput exits 0 if
     the terminal has the capability and 1 if it does not, without further action.

     If an attribute is of type string, and takes arguments (e.g. cursor movement, the termcap ``cm'' sequence) the arguments are taken from the
     command line immediately following the attribute.

     The following special attributes are available:

     clear	   Clear the screen (the termcap(5) ``cl'' sequence).

     init	   Initialize the terminal (the termcap(5) ``is'' sequence).

     longname	   Print the descriptive name of the user's terminal type.

     reset	   Reset the terminal (the termcap(5) ``rs'' sequence).

EXIT STATUS

     The exit status of tput is as follows:

     0	     If the last attribute attribute argument is of type string or integer, its value was successfully written to standard output.  If the
	     argument is of type boolean, the terminal has this attribute.

     1	     This terminal does not have the specified boolean attribute.

     2	     Usage error.

     3	     No information is available about the specified terminal type.

SEE ALSO

     termcap(5), terminfo(5)

STANDARDS

     The tput utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     The tput utility appeared in 4.4BSD.

BUGS

     The tput utility cannot really distinguish between different types of attributes.

     Some termcap entries depend upon having a '%' in them that is just a '%' and nothing more.  Right now we just warn about them if they do not
     have a valid type declaration.  These warnings are sent to stderr.
