Final answer:
Normal urine is yellow to amber in color and looks clear. Abnormal colors, such as nearly colorless or very dark urine, may indicate various conditions such as excessive fluid intake or dehydration. A reddish tinge in urine is often a sign of blood in the urine.
Step-by-step explanation:
Normal urine is yellow to amber in color and looks clear. If urine is nearly colorless, it could be a sign of excessive fluid intake, or it might be a sign of diabetes. Very dark urine may indicate dehydration, but it could also be caused by taking certain medications or ingesting some other substances. If the urine has a reddish tinge, it is often a sign of blood in the urine, which could be due to a urinary tract infection, kidney stone, or even cancer.
