The sun appears reddish early in the morning as well as in the evening because at that time most of the blue colour present in sunlight has been scattered out and away from our line of sight leaving behind mainly red colour in the direct sunlight beam that reaches our eyes.
At the time of sunrise or sunset light has to travel the greatest distance to the atmosphere to reach us. Most of the shorter wavelength blue colour present in it is scattered out and away from our line of sight During this long journey of Sunlight. The Rising Sun or setting sun consists mainly of longer wavelength red colour due to which the sun appears red.

Answer:
During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the sun and the sky appear red
