problem getting tif files to download in color

JSL

I want to download some Global Mountain Explorer files from this site : https://rmgsc.cr.usgs.gov/gme/  that show different classes of mountains, but the tif files all show up as pure black in GM.  Any suggestions on how to get the color to import?
