Sun appearing reddish during sunset - Teachoo.jpeg

Early in the morning, suring sunrise, the sun is near the horizon.

Hence, the sunlight has to travel a large amount of distance through the atmosphere to reach us.Why 

Due to travelling such a long distance, most of the blue colour (since it has short wavelength) in the sunlight get scattered.

Hence, the light reaching our eyes during the sunrise mainly consists of red colour (since it has a longer wavelength).

Hence, the Sun and the sky surrounding it appears reddish early in the morning.
