   In the old days, some subway systems used color codes to identify stations for   
   those who couldn't read.  Going way back that represented many people from   
   immigrant groups.   
      
   The NYC subway used color codes, but the system was so large that the coding   
   became very complex and hard to follow.  In Phila it was useful.   
      
   I agree that pictograms are hard to read, especially when small.
