Answer 1

Air molecules scatter away the shorter wavelengths of light (violet and blue) and the only light which penetrates through the atmosphere are the longer wavelengths of light (yellow, orange and red) which produce colorful sunsets.

Answer 2

Light is scattered by molecules in the atmosphere and by particles in the atmosphere, especially water droplets.  But microscopic salt crystals over the ocean cause additional, interesting scattering.  Even pollution may have its bright side.  Different sizes preferentially scatter different wavelengths of light.  The right thickness of clouds can appear to glow.  The general phenomenon is called Mie scattering.

Here's a handy graphic and explanation in above picture


he area around the sun generally looks red-yellow at sunset (or sunrise) because the other colors have been scattered.  But "sunset" generally includes all those other colors in the sky.  When we are lucky, sunset colors the horizon and the sky well above the horizon.  Those colors come from the light that was scattered:  the blues, greens, purples, and even some reds, pinks, oranges, and yellows.  What makes a really great sunset is the right amount of water vapor, thin clouds, and even a few particles that direct that scattered light back toward our eyes.
