François,

Is the input TIFF file a greyscale single band image?   If so, they
a greyscale output would seem appropriate. 

If the input TIFF file is pseudocolored, then you would need to first
convert it to RGB format and then encode that to JPEG. 

eg. 

pct2rgb.py tmp/F056606.TIF tmp/very_temporary.tif
gdal_translate -of JPEG -co WORLDFILE=ON \
  tmp/very_temporary.tif  tmp/F056606.JPG
rm tmp/very_temporary.tif

If this doesn't cover your situation, perhaps you could provide a
gdalinfo report on the input file. 

Best regards,
