We are ingesting NTIFs and converting them to GeoTiffs using:

gdalwarp -t_srs EPSG:4326 -dstalpha -tps

Then, when only 1 of the geotiffs are being displayed the colors are not 
distorted.  However, once we switch to 2 or more being displayed, the colors 
become distorted.

If we don't process the NTIFs to have the extra space be transparent from the 
alpha band, the extra space will instead have "data" and be displayed correctly 
no matter how many geotiff's are displayed.

Is this just how the geotiff's are displayed or is there some configuration 
that can prevent colors from being distorted?
