In MERC.H

/*
 * strip color code function for support of color limiting for commands
 * by TAKA of GhostMUD June 2001
 */
void strip_mortal_color(char *bufin, bool GLOBAL);


In ACT_NEWC.C (or at the bottom of any ACT_xxx.C)

/*
 * strip color code function for support of color limiting for commands
 * by TAKA of GhostMUD June 2001
 *
 * NOTE: You may need to use a different symbol preceeding color
 *       or for the color codes listed. You may also wish to exclude
 *       more or less colors. Also not everyone has clear screen
 */
void strip_mortal_color(char *bufin, bool GLOBAL)
{
	const char *pointer;

	for(pointer = bufin; *pointer; pointer++)
	{
		if(*pointer == '{')
		{
			pointer++;
			bufin++;
			if(*pointer == 'z') /* blinking */
			{
				*bufin = ' ';
			}

			if(*pointer == '`') /* line feed */
			{
				*bufin = ' ';
			}

			if(*pointer == '0' && GLOBAL) /* clear screen */
			{
				*bufin = ' ';
			}

		}

		bufin++;
	}
}

Now in ACT_COMM.C I have global consolidated channels code so fo GhostMUD do this
find
void open_channel ( CHAR_DATA *ch, char *argument, char *type, const int bitname)
{
   	char *buf2;
	char buf[MAX_INPUT_LENGTH + 80];
	DESCRIPTOR_DATA *d;

    if (argument[0] == '\0' )
    {

      	if (IS_SET(ch->comm,(bitname)))
      	{
        	sprintf( buf, "{W%s {Gchannel is now {RON.{x\n\r", type);
			send_to_char( buf ,ch);
        	REMOVE_BIT(ch->comm,(bitname));
      	}
      	else
      	{
        	sprintf( buf, "{W%s {Gchannel is now {ROFF.{x\n\r", type);
			send_to_char( buf, ch);
        	SET_BIT(ch->comm,(bitname));
      	}
    }
    else
    {
    
add right here the following code
		/*
		 * This limits color codes blink, clear screen and line feed
		 * over global channels to only immortals
		 * Taka 
		 */
		if(!IS_IMMORTAL(ch))
			strip_mortal_color( argument, TRUE );


in ACT_INFO.C I changed title to this
void do_title (CHAR_DATA * ch, char *argument)
{
    if (IS_NPC (ch))
        return;

    if (argument[0] == '\0') {
        send_to_char ("{RChange your title to what?{x\n\r", ch);
        return;
    }

    if (strlen (argument) > 45)
        argument[45] = '\0';
	
	/* not even imms can use these here */
	strip_mortal_color( argument, TRUE );


    smash_tilde (argument);
    set_title (ch, argument);
    send_to_char ("{GTitle changed.{x\n\r", ch);
}

Notice not even immortals can use these in titles.

in do_say i added
	if(!IS_IMMORTAL(ch))
		strip_mortal_color( argument, FALSE );
