No it is not usual. Activated charcoal is used to remove color pigments from foods in the food industry. When charcoal poultices have been placed over the kidneys it has been reported by some that the white edges of the poultice (cloth or paper) turn yellow while the poultice reeks of urine.
Usually colored urine is an indicator of drinking too little water. If one drinks adequate water the urine will appear clear. Beets, carrots, asparagus and other vegetables are known to rapidly and profoundly affect the urine in some individuals.
Activated charcoal has been reported to relieve UTI in some severe cases, but the association of charcoal use and colored urine seems to be an anomaly.
