Maybe it's just a matter of choosing a color ramp?
In the properties window for the *.tif raster, in the General section, 
choose "Pseudo Colors" instead of "Gray scale". If that displays the 
tiff with a selection of colors, then you'll want to switch to "Color 
map, and then go over to the Colormap section and set up how many 
classifications, and what colors for each...
