Can you elaborate it???

ok let me elaborate it
in my view there colors doesn't change because sky is only of gases and after it there is only space with hydrogen gas i think
coming to sea it consists of water only so it don't change color
finally my theory is when sun lights falls on things it will visible to us to see
so on different views we see different colors on sky and sea
when we see on ecllipse it visible dark and almost visible like black color
so it depends on our view and on sun light appearing on them

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. The colours of light are distinguished by their different wavelengths. The visible part of the spectrum ranges from red light with a wavelength of about 720 nm, to violet with a wavelength of about 380 nm, with orange, yellow, green, blue and indigo between. The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.MAINLY can be explain by tyndall effect and reyleigh creterion as per i know.

How about the sea???

I know the answer.
Light consists of spectrum of various light.For example green,yellow,UV,infrared etc.
So consider a body which appears say red.I appears red because,that body absorbs all colors but emits only red colour.
Now Water.The blue color is of minerals or algae present in it.These minerals absorbs absorbs all light but emit only blue light.
So water appears blue in color.If they emit any other light then it would appear of that particular color.
Now sky.It is actually an envelope of various layers of material.These materials(Various gases and dust particles) emit only blue light.
So it appears blue.

I hope it satisfies you.😁

@ishu: but your theory doesn't satisfies when it is time of sunset and sunrise

My theory does support every thing.I am saying,if a thing has a particular color then it is emissions of that color.At night the particles are not having any light they are having radiations of other wavelength.so they are emitting radiations of black color.

@ishu: lol i think it would be better if you mentioned it before and almost my theory and yours are almost equal

How about the sea???
same for sea
:-The sea reflects the sky
:-The sea refracts light just as the sky does.
Blue light is more easily bent, or refracted, than red light; thus, light refracted back from the surface of the sea appears blue. Furthermore, when you are underwater the water around you appears blue because more blue light is scattered back to your eye than red light.
You have probably noticed that the sea is not very blue-looking when the sky is overcast. Water reflects and scatters the light that strikes it; this is shown by the fact that you can see your reflection in puddles. When the sky is brilliant blue, the sea is also, because it reflects the blue of the sky
The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision.Here there is no case of red or green so it appear blue.
I remember a fact next time you're on Facebook (which is probably now...) take a look around at the aesthetics of the site. What color do you notice as being the dominant color? Your first response should be blue. That's right, blue is the dominant color of Facebook and that is not by accident.Becoz mark is colorblind cannot respond to red or green hope so you might be knowing .
