amber colored urine? dehydration? . i had 3 cups of coffee and a red bull today all in 4 hours. the first time i urinated it was an amber color. then i got worried and drank a lot of water and now my urine is back to normal (light yellow). this only happened once after drinking all that caffeine.
more concentrated urine in the bladder can be darker. as long as your urine returned to a more-normal light yellow color after you drank more water there is no need to be concerned.
