ELI5: I drink plenty of water everyday, but why is my urine always yellow?

Similar to how your fesces are the waste product of the food you eat, your urine contains the waste liquids from the stuff you drink. "Urobilins" are what give your urine the yellow colour.

If your urine is clear, it's probably because you're drinking more water than your body needs. If your urine is dark, then you're probably dehydrated. Your urine should be a light yellow colour, which indicates a healthy balance.
