I see that the default map contour is gray. With a white background, it<br>
means that my contours are barely visible (example attached, yes there<br>
are islands plotted in there!). I am wondering what I could change to<br>
make the map contour in black instead. I have attempted to change<br>
several settings, including:<br>
<br>
 res@mpGeophysicalLineColor = &quot;Black&quot;<br>
  res@mpNationalLineColor   = &quot;Black&quot;<br>
  res@mpGridLineColor       = &quot;Black&quot;<br>
  res@mpLimbLineColor       = &quot;Black&quot;<br>
  res@mpPerimLineColor      = &quot;Black&quot;<br>
  res@mpDefaultFillColor    = &quot;Black&quot;<br>
  res@mpLandFillColor       = &quot;Black&quot;<br>
  res@mpNationalLineColor   = &quot;Black&quot;<br>
  res@mpFillBoundarySets = &quot;Geophysical&quot;<br>
<br>
...and a few oddball things that I found by Googling this question. Nothing has changed the gray map outline.<br>
I also added black to my color table.<br>
I will appreciate any help or advice!<br>
 <br>
Cheers,<br>
