The sun gives off lots of different colors of light. The wavelength of light determines what happens to it when it strikes our atmosphere. Blue light is scattered much more easily by atmospheric gasses than other colors of light (because of its wavelength).
The sun's light contains lots of different wavelengths of light which, when seen together, look yellow. That just happens to be how they look. That is also why the sun appears to be yellow when you look at it. When you see the sun in the sky, the light is, of course, not just hitting you, but is hitting your half of the earth's atmosphere. When it hits the atmosphere, blue light immediately begins to scatter, and some of it scatters towards you. That is why you see blue light everywhere in the sky on a sunny day.
Red light scatters too, but not nearly as much as blue light. So when the sun is setting, and light must travel through a lot more atmosphere to reach you than when the sun is in the middle of the sky, the blue light all scatters away before it reaches you. The red light does not scatter completely away, but spreads to create the beautiful red sunsets that we are used to seeing.
That is why the sky is blue and sunsets are red. It is not because of pollution. It is not a special property of nitrogen or of oxygen.

The sky is blue due sun's light refracting through the gases in the atmosphere. One interesting thing to note is that the sky appears darker directly overhead than it does nearer the horizon. This is because you are looking through less of the gases that colour the sky through to outer space than if you look towards the horizon.

It isn't. That is how your eyes percieve it. Light is refracted? and makes it appear that way, though people see "colors" differently.
