See below: Is urine dark yellow throughout the day or only first void of the day? Do you take vitamin b complex? Do you take any medications? First-void urine tends to be darker because we haven't been drinking during sleep. Certain b vitamins can turn urine a bright yellow color. Some meds contain tartrazine in the coating, which may color urine. If you have burning/ pain, urgency, frequency, see doc.
