I was able to get everything working fine, I've got !colorbar4 and !colorbar5. Everything seemed to work fine with !$5, so I left it. Here they are:

Code:
on 1:text:!colorbar4 *:#: {
  if (!$5) { msg $chan Invalid Format.  Use: !colorbar color1 color2 color3 color4 nickcolor nick | return }
  msg $chan $+(,$2,$chr(44),0"¼0,$chr(44),$2¼»,$3,$chr(44),$2"¼,$2,$chr(44),$3¼»,$4,$chr(44),$3"¼,$3,$chr(44),$4¼»,$4,$chr(44),$4"¼,$4,$chr(44),$4¼»,$5,$chr(44),$4"¼,$4,$chr(44),$5¼»,$5,$chr(44),$5,------,$6,$7-,,$5,$chr(44),$5,-----,,$4,$chr(44),$5"¼,$5,$chr(44),$4¼»,$4,$chr(44),$4"¼,$4,$chr(44),$4¼»,$3,$chr(44),$4"¼,$4,$chr(44),$3¼»,$2,$chr(44),$3"¼,$3,$chr(44),$2,¼»0,$chr(44),$2"¼,$2,$chr(44),0¼»)
}
