That's surprising. Are you sure the viewer is using overviews properly ? You 
could try "gdal_translate tiled_test.tif.ovr ovr2.tif" and display ovr2.tif. 
If it looks OK, then it's likely an issue with the viewer. If it is greyscale 
then there's a strange issue for which sharing your dataset would be good for 
further investigation.
