Why did my pool turn blue?

TFP water will never reflect turquoise, it is completely clear. On a sunny day it will always reflect blue. On a cloudy day, as in the pictures, it will be a blue/green. If the water actually has a color, there is a problem.
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see.

It did not have a blue color when we filled it. Now the water itself is visible blue. That is what I was trying to show in the two pictures....the change from turquoise when it was first filled, to blue, now.TFP water will never reflect turquoise, it is completely clear.

Not sure if this would be a definitive explanation, but in Post #1 the pool appears newly installed and the water is not as clear. In Post #2 the pool appears to be more established with coping now completed. The water looks more clear in Post #2 and perhaps better balanced. I wonder if some of the light/color spectrum differences might have been influenced between the two time frames due to the new water with suspended particulates still being balanced/filtered? Of course the sun's lighting/UV and cloud cover at the time of each pic can also influence how we perceive our pool colors. Just a thought.

Of course it's all gradient of greys, but typically, grey reflects blue back at your eye and lighter colors reflect more turquoise to green. My light grey reflects blue in bright sunlight and turquoise in overcast. This can change over the course of any day from dawn sun to high noon to dusk. Your pics appears to be overcast condition.
