The article apparently deals with creating multiband rasters (which I am 
already able to do), but not storing/displaying a different band name in 
QGIS.

I wasn't able to find anything on which format format ArcGIS uses to 
store band names (and I can't check since I do not own a license). For 
now I'm storing the band name in a "Band" PAM metadata item for each 
individual band in the GeoTiff raster, e.g. gdalinfo prints the following :

     Driver: GTiff/GeoTIFF
     Files: test.tif
     Size is 4850, 4340
     ...
     Band 1 Block=4850x1 Type=Float32, ColorInterp=Gray
       NoData Value=nan
       Metadata:
         Band=GREEN

In QGIS this is displayed properly under the "Metadata" tab, but I 
wasn't able to display band names elsewhere. If anybody has an idea on 
whether this is doable, I'd appreciate any help.

Cheers,
François-Xavier
