Why is pee see through?

Pee, or urine, is primarily made up of water, which is why it appears clear or see-through when it is diluted. The concentration of waste products, such as urea, creatinine, and electrolytes, can affect its color; more concentrated urine tends to be darker. Additionally, hydration levels play a significant role—well-hydrated individuals typically have clearer urine, while dehydration can lead to darker hues.
