I changed the script around a little bit. The "*." in many of the $LS_COLORS items is causing the problem. I couldn't figure out how to fix it in the for loop echo -e so I used sed to change the values before entering the loop. The 7 in 7z was also causing some issues, at least on my system. Here is the end result that I think does what you want:

Code:
#!/bin/bash
# color_meanings: explain meanings of colors used in bash ls

CLEAN_COLORS=`echo $LS_COLORS | sed -e 's/\*\.//g'`
{
        IFS=:
        for i in $CLEAN_COLORS
        do
		echo -e "\e[${i#*=}m$( x=${i%=*};echo "$x")\e[m"
        done
}

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       int echo(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.
