Why do we feel like the Sunlight is yellow?
Here on Earth it's yellowish but in space it's white. But on Mars with atmosphere the sunlight is bluish. Why?

The Sun is very slightly on the yellow side of white; call it off-white.
The color temperature of the light from the Sun in the sky is 5780K. In space above the Earth's atmosphere, the color of the Sun is 5900K.
The color of daylight (the Sun and the blue sky together) is defined as 6500K (Standard Iluminant D65).

Earth's atmosphere scatters light making it appear slightly yellow from earth just like how the sky appears blue..for example if you were on The Moon the sky would be black because there is no atmosphere to scatter any light..and the sun would be pure white

The sun's surface radiates as a blackbody spectrum, the wavelength of its radiation determined by temperature. At about 5,800° K, that places the peak radiation in the yellow-green part of the visible spectrum. It appears mostly white to us, however, because it is also a mixture of other wavelengths, although in slightly lesser amounts.

Amazingly despite all these answers only GeoffG is anywhere near correct. Come on guys you can do better.
The sun is actually white. If it as yellow, white paper would look yellow in sun light, it doesn't Rayleigh scattering has very little effect on it's colour as it turns out. In reality few of us have looked at the sun for more than a few seconds doing so can cause permanent eye damage.
The real reason is't known but it is speculated that it is either caused by your brain measuring the suns colour against the blue of the sky, or by the fact that we only really look at the sun when it is low down.
Whatever the reason the sun is white in the optical.

It is yellow in comparison to the blue sky. It is actually (in space) slightly greenish.

Light emission from the photosphere (which we describe as the 'surface' of the Sun) occurs at all visible wavelengths - hence it appears white. However due to variations in the levels of scattering caused by atmospheric interference, as well as the sensitivity profile of the detector, sunlight can appear subtly different colours.

Of course! Both rayleigh scattering and plank relation rips completely off the uncertainty charts when influenced by such energy, ninety-five percent of the solar systems total mass and a UV bombardment that will fry humans like eggs.

Color of Sunlight as seen on Earth's surface during day is yellow due to Rayleigh Scattering.
Our Sun is actually white (mixture of all wavelengths of visible spectrum) if we see it from outer space or high-altitude airplanes. Our atmosphere scatters shorter to bigger wavelengths color from sunlight when the white light travels through it. During day, it scatters violet and blue colors leaving yellowish sunlight (the reason why sky is blue and sunlight is yellow). During morning and evening, the sun appears reddish because light rays needs to travel longer distance in atmosphere which causes scattering of yellow light too.
