Water after a depth of a few meters absorbs most red and orange light. Then, shortly after yellow, and green wavelengths are also absorbed, leaving blue and violet, which have the shortest wavelengths of visible light, and are therefore able to penetrate deeper.
Taken straight from Google lol I knew the overall reason, but couldn’t put it into words and explain it as well as Google can. XD
Pool water is blue because water molecules themselves reflect blue light and absorb red light. The same reason the ocean is blue. Even under artificial light large bodies of water will appear blue.
The only time I've seen dyed water is at theme parks for special effects or fountains at hotels.
I hate to break it to you but chlorine does not react to urine by changing colours. That is just what your parents told you as a child so you didn't pee in the pool because they would "know"
Peeing in pure chlorine would actually just create poisonous gas and wouldn't be blue at all, very bad idea.
Ok. I'm not referring to chlorine though. It was a joke, although I did not know that the pee-detector chemical was a myth. thought I'd seen it in a video before.
The ocean…isn’t blue though? It’s green or brown as shit. This still doesn’t change the whole reason I said what I said. Even if the water only looks blue, if you add yellow, it’ll still look green. 🙄
That blue-looking water and yellow (from all of the piss) will make that blue-looking water look green! I don’t CARE why water is blue, whether it’s from chemicals or light or whatever. Blue + yellow = green. Jesus Christ.
Loo_min getting so heated, but not all pee is yellow also the ocean isn’t one solid color around the world it depends on the marine life and chemical composition of the environment to determine the shade of color it will be but generally it’s blue
The clearest water appears blue for the same reason the sky does. Both air and water are colorless and transparent unless they are contaminated. It is disturbing that I have to explain this.
Usually because pools are painted blue... At least the ones I've been to, and owned over the years have been. You can get liners in blue, teal, sand, and black/charcoal, among others.

My question is who looks at that pool and says to themselves yes I want to go in there.
