What causes the change of urine color?

Urine color can change due to various factors, primarily hydration levels, diet, and certain medications. Dehydration typically results in darker urine, while increased fluid intake dilutes it, making it lighter. Foods like beets or berries can also alter urine color, as can certain vitamins and medications. Additionally, health conditions may cause abnormal colors, such as blood in the urine leading to a red hue.
