sunlight is made up of all the colors of the rainbow:red,orange,yellow,green,blue and violet.
the gas molecules in the atmosphere interact with the sunlight before the light reachs our eyes.
The gas molecules in the atmosphere scatter the higher energy(high frequency) blue portion of sunlight more than they scatter the lower energy red portion of the sunlight(this is called rayleigh scattering).the sun appears riddish yellow and the sky surrounding the sun is colored by the scattered blue waves.
when the sun is lower in the horizon(sunrise or sunset) the sunlight must travel through a greater thickness of atmosphere than it does when it is overhead and even more light is scattered(not just blue but olso green,yellow and orange) before the light reaches your eyes.this makes the sun look much redder
