As far as I understand it, Erythrocytes can color the urine from red to tea and cola-color...
Myoglobin can color urine red (there is no blood involved) and there are many other substances that can color urine red.
In ochronosis - there is homocysteinuria and urine turns black after(!) urination due to its oxidation.
