Why does urine look colourless when being released, but appears yellow when you pee into something and look into it?
In: Biology
Color comes from the light that makes it to your eyes. The stream of urine is really thin and uneven so the little yellow color there isn’t as noticeable. Once it is in a container you are looking at a thicker collection with less light refecting texture than was in the stream. The yellow coloring adds up and you see it more.
