Now doctors at a U.S. medical centre have drawn up a diagram to illustrate what is normal and what is not.
The chart, developed at the Cleveland Clinic, in Ohio, says urine usually ranges from a deep amber or honey colour to a light straw colour, with many shades in between.
The Cleveland Clinic, in Ohio, has created a diagram which shows all of the different possible shades of urine colour and what they say about your health
It says the colour of a person's urine says a lot about what is going on inside their body, and that people should take heed of its warnings.
The diagram shows that if a person's urine has no colour, it suggests they are drinking too much water and should consider cutting back.
