Transmitted light (from the sun, light bulbs, fire, etc) is made up of a spectrum of colors. The longest wavelengths of light are on the red end of the spectrum and the shortest wavelengths are on the blue/violet end of the spectrum.
Why is the sky blue, you ask? Blue in sunlight collides with air molecules and our eyes see it as blue.
not becuase the ocean is blue thats some made up B.S.

The sky appears blue die to the interaction between the atmsophere and the different wavelengths of light within the visible spectrum.
Sunlight consists of all colours of the spectrum, each colour being a different wavelenght of light. Some of these waves pass easily through the atmsophere, others are scattered. The combination of colours that reaches is appears as blue. When the sun is low on the horizon (eg sunset) the sunlight strikes the atmosphere at an oblique angle and passes through more atmosphere before reaching the observer, more light is scattered and the combination of lightwaves reaching the observer give the sunset it's oragne, red, yellow and pink colours.
The scattering effect is called Rayleigh Scattering and is explained with the aid of diagrams in these sites -

Original light is made up of 7 colors. When it shines on earth, blue light is scattered(reflected) by the air. For example, When light shines on a green box, the box reflects the green light and absorbs all the other colors. So, it is green. Black things absorbs all the colors. White things reflect all the colors. But when light shines all the other colors pass through the air to the ground. So, the sky is blue.
And thats why the ocean is blue.

The sun reflects off the ocean witch is blue and reflects on the sky.Thats why when the sun is down at night the sky is black.

When light passes through the upper atmosphere, the blue light gets scattered down to Earth, whil the redlight goes straight through. Blue light gets scattered more because it has a shorter wavelength.

Its the pigment that we see in the spectrum. the sky isn't always blue

In fact dear it is Black. Due to the air (atmosphere as you may call it ) it appears blue. Nice answer na by the way?

Because God made it that way and He gets what He wants.
