<div>Just curious why the color overlays in topo map example 9 &quot;<a href="https://www.ncl.ucar.edu/Applications/Scripts/topo_9.ncl" target="_blank">https://www.ncl.ucar.edu/Applications/Scripts/topo_9.ncl</a>&quot; have an exclusive red tint when &quot;ps&quot;, instead of &quot;png&quot;, output is chosen. I changed nothing except the output option. Is there a way to
 get &quot;ps&quot; with a slight change?</div>
<div><br>
</div>
<div>thanks,</div>
