See answer. The color of the urine is usually either a reflection of the state of your hydration (dehydration: dark urine); or due to a pigment from a dye in your food, vitamins (especially vit b2 riboflavin- orange urine), or medication causing discoloration; or sometimes blood in your urine coming from the kidneys (dark brown or red). I suspect the former two causes and not the latter cause in your case.
Several causes. There are several possible causes for colored urine including food colors, medication etc; could also be due to underlying kidney problems. Check with your doctor if not better or worse.
