Why does sun appear red during sunrise but sky appears blue?
Ans: This is due to the way that light particles diffues or pass through different amounts of differently coloured light. White light is made up of all of the colours in the spectrum, like shown in a rainbow, and when the light (generated from the sun) passes through our atmospher, all other colours of light except for blue are filtered out by the light passing through the atmosphere.

During evenings, or indeed some mornings, the sun is lower in the sky, this means that the light from it has to pass through a greater amount of atmosphere to reach the point that you are at. Due to this, it now filters out all parts of the light spectrum except for the red light, meaning the sky appears red. This is also why, on some rare occasions, the sky can appear green.
