In brief: Myoglobinuria
Very, dark urine with the color of cola could be due to the presence of myoglobin, which is a breakdown product of muscle cell.
It can be caused by trauma, alcohol, medications, and vigorous exercises. It could indicate that you have rhabdomyolysis, which could lead to kidney failure. Another cause would be blood (as in uti) or bilirubin in the urine (as in liver disease). Should be checked.
