Three things: 1. Some stars are of such a temperature that much of the energy is in the form of red light (we call these "M" stars); 2. Doppler effects of rapidly receding stars shift their light towards the red of the spectrum (hence, "red shift"); 3. obscuring dust, either in space or the atmosphere (happens every sundown).

Why are distant stars redder than nearby stars of the same spectral type?
The reddest stars are the stars that are considered the coolest. Blue light is more effectively scattered than Red light. This is called ``interstellar reddening".
Interstellar reddening is caused by what?
A downward shift in frequency of radiation (perceived as reddening in the visible spectrum) is observed in most stars outside the Milky Way Galaxy. This red shift is assumed to be caused by the stars moving away from our galaxy at a sizable fraction of the speed of light. This shift is similar to the Doppler effect in sound.
