small problem in displaying MAPGEN files

Hi,
  When I run show.sh in MAPGEN it gives the following error message.

Color: can't set color 91312
Color: can't set color 91312
Color: can't set color 91312
Color: can't set color 91312
Color: can't set color 91312

  Any clue as to why is it happening and the get around would be appreciated.

Thankyou,
