Protection may be achieved by changing ordinary colours to red. Red Ocher is used in many ceremonies, and in especially large amounts in exorcisms. Red may denote flesh. Some skirt tassels of gods depicted in sandpaintings are black and white with a small red dot between them symbolzing flesh, especially of rare game - this is a symbol of plentiful meat. Incensing is a conclusive act.
Fire is the symbol of annihilation, and is said to burn evil.
There appear to be no figures, however, for the number of Navaho practicing some form of traditional religion.
