For instance, trace amounts of limonite impart a yellowish brown color; serpentine, hornblende, and diopside produce varying tones of green; minute quantities of hematite, vesuvianite, and garnet introduce a reddish brown hue; sphene, epidote, and chondrodite give a yellow tinge; and plant and animal remains produce shades of dark gray to almost black.
