The sky is not really blue either , yaknow, it’s more a gray..
The sky REALLY doesn’t have a color. What we see is an optical illusion given off by refracted light from the Sun. At night, you see what color the sky really is.
Sky has no color. The blue we see is the blue light wavelength getting through or around the atmosphere molecules in greater quanties than other colors of sunlight.
This ocean color thing could be a backdoor trick, because just the other day the Greenies were saying the plankton was dying. Plus they had to cook up something to splain why all their doom and gloom “worst hurricane season in history” predictions are not proving out.
Like mama told us, “you tell a lie and then you have to tell 5 more to cover the first one and 5 more to cover them and before long you can’t remember what was the truth”. The Globull Warmers can’t remember what the truth was.
Closer to the equator the sky is more grayish due to moisture content, but way up north in the dead of winter the sky gets a very rich blue.
