Dark Yellow Urine
A darker yellow color may be a sign that you need to drink more fluids. Your body concentrates your urine when it lacks enough water.
 Tip: Increase your water intake throughout the day, especially in hot weather or during physical activity.
Orange Urine
Orange color can be caused by dehydration, but sometimes also by certain foods or medications. In some cases, it can be associated with liver or bile problems.
 Important: If the color persists, you should consider seeing a doctor.
