This is due to phenomenon called as scattering of light. At noon sun is directly overhead so the light rays coming from sun absorb all the visible colours thats why we see sun white coloured. But in evening sun is far away as compared to noon.

During sunrise and sunset, light has to travel the farthest than during the other parts of the day to reach the human eye. As the distance of travel through the atmosphere increases during dawn and dusk, light is refracted much more than during noon. Thus the colours of the light having shorter wavelengths fade out leaving only the red wavelength that reach our eyes.
You can see that the scattering of light is more when the Sun is near the horizon. As the shorter wavelengths are scattered, only red light is left, as it has the largest wavelength of the seven colours. Thus the sun appears red during sunrise and sunset.
This also results in refraction making the Sun look bigger during the sunset and sunrise than during the noon.
