What does it mean when you pee & you wipe & the urine is a yellow color?

Normal urine. Normal urine is some shade of yellow, darker if dehydrated, lighter if well hydrated. Cola colored urine is worrisome for liver disease.
Urine color. Urine is normally yellow. The color of urine varies with how much fluid you drink. Drink a lot of fluid and your urine will be very light, like the color of water. Don't drink very much and it gets darker yellow, maybe even brown. Certain diseases, most notably hepatitis with jaundice, makes the urine very dark (brownish). If you don't have any other symptoms, you don't need to worry.
