Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight by the atmosphere is the main reason light from the sky is blue.

Ok let's start at the beginning. All light is originally WHITE. As it comes in contact with water drops and other chemicals and "debris" in the atmosphere it begins to bend. This is similar to how a rainbow is formed- in a rainbow the light is REFRACTED into the colors we know. In the sky, the white light is bounced around and refracted several billion times. The only color of light that reaches us is the blue one. Others may be scattered too much for us to see. This is the same idea that causes the sunrises and sunsets to be so colorful. The sun's light is shining through a different part of the atmosphere so the colors are being bent in a different way - all relative to us standing on earth.
The sun is actually yellowish-orange and it has to do with the amount of heat it has. There is a scale amongst the colors- called the HR Diagram, where you can see based on temperature, what color different stars will be.

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.
Why is the Sun yellow?
It isn't, really. The color yellow is a purely human interpretation of a collection of radiation that hits the retinae of our eyes and gets processed by our visual cortex

Sun is yellow because thats the colour of the hydrogen burning, the sky is blue because of the refraction of the light from the sun.

Becuase the government is all like 'OoOo..extraordinarily hues...permit's make this that and that this' so as that they made the skt blue the grass green and the solar yellow just to spite all individuals different people who needed the sky green the grass..nicely not lifeless-yellow yet a effective yellow and the solar blue! haha..j/ok i'm in simple terms on a sugar-hyper-thingy

The sky is blue, due to the doppler affect. Blue light has a short wavelength, while red has a long one. That means we see more of the blue waves than the red ones as some of these go straight past us, giving the sky its blue colour. This is why the backs of vehicles often have red lights, think a police cluster, as you can see the red for a longer distance as its going away from you, due to its long wavelength.
As for the sun being yellow, I imagine it is just because it is a big ball of flames.
The sea is blue, because generally it is reflecting the colour of the sky.

Well the sky is blue because light particles come from the sun into the earth's atmosphere and turns blue.The sun is yellow because ,
guess what, the sun is made of fire and flames are so hot they turn yellow.A fact for everyone : the sun's outside is hotter then the sun's core (centre).And another answer is that the lord god made it that way.

hmmm, wouldn't e-mail charleslloyd's too soon. Last i heard the sun was the centre of our solar system.
Ask the question about the sun in science and as for why the sky is blue ... check out what others got as an answer when they asked an identical question:

The sky is blue because of the atomosphere and because of the water reflesting off of it. The sun is yellow thanks to the gasses in the sun, which makes it hot. But the sun is not only yellow. It's yellow and orange and even some blue in there. The different colors tell how hot it is.

The other answers are good enough but consider this if you will.
They say Bees see yellow as blue that makes it rather confusing doesn't it?
Perhaps they do not know we have a sun !
