The presence of abnormal colours may indicate the presence of inorganic pigments (e.g. copper, nickel, or cobalt salts), dyestuffs from tablets, capsules, medicines, pesticides, and rodent baits, especially those containing warfarin, reserpine, chloralose, or diphenadione. Common rat-bait coloms are blue, green, or red and are usually associated wifti oafrneal or cereal grain.
