What causes urine color to change?

As mentioned above, the color of your urine is primarily determined by how much water you’ve had to drink. When you drink lots of water, your urine can become so light that it appears to be almost clear. The less water you drink, the darker your urine will become.

Diet, vitamins, and minerals

Diet can also be a factor. The color of all-natural foods (such as berries and beets) can interact with pigment to create a different color. Heavily processed foods can contain high amounts of food dye. This dye will interact with the pigment as well.

B vitamins, such as riboflavin (B-2) and cobalamin (B-12), are also known for causing fluorescent yellow-green urine. If you take supplements or multivitamins, they may be the source of your brightly colored urine.
