Why Does the Sky Looks Pink?

Because the sun is low on the horizon and sunlight passes through more atmosphere at sunset and sunrise than during the day. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. Reflected light has longer wavelengths, longer wavelengths of light shade red, thus you get the pink in the sky.
