The sunset is often more brightly coloured than the sunrise, with the shades of red and orange being more vibrant. The atmosphere responds in a number of ways to exposure to the Sun during daylight hours. In particular, there tends to be more dust in the lower atmosphere at the end of the day than at the beginning. During the day, the Sun heats the surface of the Earth, lowering the relative humidity and increasing wind speed and turbulence, which serves to lift dust into the air. However, differences between sunrise and sunset may in some cases depend more on the geographical particulars of the location from which they are viewed.

The atmosphere absorbs the blue end of the spectrum of colors present in sunlight. The thicker the atmosphere, the more of the blue end that is scattered. When the sun is directly overhead, or at least at noon hour, the distance the sun's rays travel through the atmosphere is the least, so the sun's color is the brightest yellow. When the light has to travel through the atmosphere from the horizon to you at sunrise and sunset, the distance through the atmosphere is much greater, so more of the blue is scattered, leaving a predominance of oranges and reds. If you draw a diagram of two concentric circles, and put the sun in the two positions, you'll see what I mean.

During the day, gases in the air reflect all light but blue so the sky appears blue to us. During sunrise and sunset, the light is bent through the atmosphere which changes it's frequency and it appears red or orange.

Edit: I don't know what the hell the guy below me is talking about. The sun doesn't heat up at all. It's constantly burning at the same temperature... Why would the sun even. OMG How ignorant are you?

There is a property of light called the Tyndall effect, which causes light with shorter wavelengths to be scattered more effectively by matter.

Visible light (like that from the sun) contains wavelengths from 380nm (blue) to 780nm (red). The shorter wavelenghs are scattered most effectively by the earth's atmosphere and are therefore percieved byt he human eye most easily - the shortest visible wavelength in solar white light just happens to be blue.

At sunset, the sun looks red. This is because the light you see has to travel through much more of the atmosphere (it reaches you at an angle, travelling sideways through the air rather than straight down through it), and the blue light is scattered to the point where it spreads out and is very low intensity by the time you see it, so the sky appears to be orange or red.

it is due to refraction of light from atmosphere
the rays coming from sun consists of seven colours which bend to different extent and the red colour bend least and thus it appears first and the other colours appear after some time

b6473d82e47c479ca94a81a5daeff14Why does the solar look pink for the time of sundown/break of day?QUOTE dirt in the ambience. have you ever observed that if there's a wooded area hearth and additionally you spot the solar in the direction of the heavy smoke, it appears that evidently pink/orange besides?

Because during sun up it is in the process of heating up and it takes time to get beyond red hot and at sun set it is in the process of cooling down and going out for the night, so it changes colors depending on how hot it is at the time of morning or evening you're looking at it.

it is because of the scattering effect of the suns ray that makes it so.. how old are u so that i can explain so accordingly in scientific terms?

pollution.
by the way, that's a funny one about the sun heating up in the morning!
