Suhaina!
Urine is not white colored unless it contains chyle ( a milky white chemical from the body).
You meant colorless I am pretty sure, not white.
Well.
The color of urine depends on the material it has in it…and how much water it has in it.
Drink more water, urine will be watery. Drink no water for a while and even for over 20 hours…urine will be less in quantity and will be darker or yellower in color.
That is not the only reason urine changes color.
Many chemicals do change color of urine.
JUst ask a specific question so one can answer specific answer.
By the way… always know what is the color of the ‘material’ you are dumping in this world everyday…
