Ever take a peek inside the toilet bowl before flushing and wonder why your pee is nearly clear one day and dark yellow the next?

Some unusual colors may be cause for concern—if your pee is pink, it’s time to see a urologist. But others could be connected to what you ate (a brown color could mean you’ve eaten lots of rhubarb and a blueish green tint can come from some food dyes).
