how to fill the map?

Dear everyone,

I want to fill the land with specified color "LightGray" by setting

 
  colors = (/"white","black","magenta","transparent"/)
  gsn_define_colormap(wks, colors)

  res1_at_mpFillOn = True
  res1_at_mpFillColor = "LightGray"
  res1_at_mpMonoFillColor = True

but the land isn't filled with "LightGray" color. However, if I add "LightGray" to the colors, i.e.,
  colors = (/"white","black","magenta","transparent","LightGray"/)

the whole map including water and land is filled with "LightGray".

Therefore, it seems that the color assigned to res1_at_mpFillColor should appear in colormap, right? but how can I just fill the land with the specified color? Thanks.

Xuguang
