Hi Adriana,
This is really strange. Try the following:
1) At the command line, enter this:
ng4ex gsun01n
This will open up an x-window and draw 4 similar plots. You can see all
four by clicking on the x-window. In the 3rd/4th plots, do you see some
color?
2) Please try switching your output format to something other than png, say
a .ps file or to a x11 window. Do you still have no color?
