While it is often described as a yellow star, the sun is really white. The color is due to it's temperature. Cooler stars are only red hot, hotter stars are white hot and really hot stars are blue. This is because hotter objects emit shorter wavelength light, and blue light has a shorter wavelength than red light.

Hi
The sun is not yellow. It looks red and then yellow at sunrises and sunsets because of the effect of the atmosphere, but if you try to look at it at mid day (don't do it without a proper filter!!!, it can be pretty harmful for your eyes) you'll see it white.
We use to remember it yellow because it looks yellow the last time we can actually see it for a few seconds, when it's near the horizon.
The sun shines because its hot plasma in the solar photosphere. This hot plasma (you can consider it's like an envelope of burning hot gas around the inner layers of the sun) glows on every color, and the mixture of all of them results in what we call white.
Then, that light goes through the earth atmosphere, and when the mass of air it has to penetrate is thick enough (near the horizon) some of the colors get scattered by air molecules (Rayleigh effect) and only the redders remain unscattered. That's why we see the sun red at sunset/sunrise, then yellower and then white.

Because is a middle aged star. It gots something to do with what's made out of and how that works. At the beginning, the sun was actually blue and some time later, a lot of time, it will be red an then explode.

there are all colours of fire in it but we notice yellow the most coz if u see a fire burning, the yellow part is the biggest and the same thing is in the sun. also there are many nuclear reactions taking place in it due to which it gives out heat and energy.

The light coming from it is mainly in yellow range. There is no other reason. At morning time, the majority of light coming from it is in red range so it is red than.

actually it is not yellow.. it has a lot of hot gases around it, but its size and distance from the earth, gives it a yellow gold look from our point of vision. Actually it is more of a reddish-orange color. You see it during sunrise and sunset...

it is a burning ball of gas. That might be a clue. Just like other stars. Yes our sun is the closest star to us.

Because we see it that way. It is the color of fire in all its hues. Red and orange and yellow.
