I'll start with why the sky is blue because it is relative to your question:
the blue color of the sky is caused by an effect called Rayleigh scattering. Basically what happens is that due to the high angle during the day, most of the red light is refracted by the atmosphere, away from us, leaving us with mostly the blue wavelengths reaching our eyes.
Now to answer your question:
At sunset, when the angle of the sun is lower relative to your viewing angle, and plus the fact that the light has to pass through more atmosphere due to the lower angle, the scattering effect refracts the blue light away, leaving only the redder colors, making for nice reddish sunsets!

well the light of the sun is actually scattered. (the colors are the rainbow colors) at that time, red is evident so thats why the sun is red and it is possible to see it at that time because the earth is rotating so the rays of the sun and the direction of the light isn't a direct hit in the area so it isn't so painful in the eyes to see the sun at that time

Sulfur in the atmosphere causes the sun to look red.

the answer is the same for both questions.the atmosphere is reflecting more of the rays because the rays have more atmosphere to go through.
