seems colorless.

Why Swimming Pools are Blue

Pool
water is blue this is due to the way molecules in water absorb light.
We know that sunlight is white and consists of all
the colors of the spectrum.
When light falls on water, these molecules in the water absorb light from the red end
of the spectrum.
By removing the red, it means that the light
reflected by the water is
slightly blue (since
the blue color has a
greater dispersion, this color remains)
The same thing happens even under artificial
lighting and the deeper the swimming pool is,
the more it looks blue.
Sometimes we see the drawings in the swimming pools. These are due to the
tiles they contain.
