Single band images need an associated color palette (some prefer to call 
it color map). Some programs just generate one default palette, that can 
be gray, when the file doesn't provide it. Maybe that's what is 
happening with you, or maybe the file has one that applied to band in 
question produces a dark image. Basically you must use one software that 
allows you to change the palette if the one you get doesn't please you.
