Is it good or bad if urine is clear and not yellow?

The color of urine. That almost sounds like the title of a movie.... In general clear urine means that the dilution is affected by the use of excess fluids, caffeine or other diuretic. This can be seen with alcohol and caffeinated beverages, and when drinking large amounts of other fluids. In an of itself, clear urine is not a disease or symptom of a disease.
