During morning and evening you are looking at the sun through a thicker atmosphere.Since the sun rays that reach your eyes enter the atmosphere at less than 90 degrees C the light rays are bent due to refraction.Of the seven colours VIBGYOR red and orange are the least deviated due to their higher frequency.So more of these colours reach your eyes than the other colours.
The thicker atmosphere,acting as a lens, is also the reason for the sun looking bigger.
During noon sun rays enter at 90 degrees and they are not deviated.

As the sun comes up in the morning, it's light has to travel through a thicker cross section of the atmosphere. This means the light encounters more particles and is scattered by them. This results in the color of the sun (and sometimes the size) being altered. As the earth rotates and the sun's rays become more perpendicular to your location, there is less atmosphere to go through, so the sun looks yellow.

It differs from view to view and from place to place. In the morning the positiong of our planet getting the sun rays is also one. The time this position move up even at 9.a.m you would see the sun in its brighter and not orange or yellow. In the North pole and south pole the sun is breif and can bring magical aurora's. It all depends on how much sunlight at a particular or full time of the day the (sun's position) vis-a-vis the amount of light falling on the earth. For more details visit National geographic or Sun Sites.

Because shorter wavelength scatters more according to Raleighs scatter law. Since during morning or evening the suns is at more distance from the place of sunset or rise. So the waves have to travel a longer longer distance. But according to our law shorter wavelength will get scattered and longer wavelength will reach the earth surface.thats why sky and sun looks red in colour during sun rise and set.

In fact, in early morning or late evening, we don't see the sun directly (real) but we see it virtually due refraction of light. Since the infra red rays having shorter wave lenght, we see it orange or yellow in the morning and the infra red rays at the other band, we see the sun blueish in evening.
