due to refraction.

Answer 2

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Where the sunlight is nearly tangent to the Earth's surface, the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red, at sunrise and sunset. (from wikipedia.com) Also from what I've been told, oxygen, although transparent is slightly blue.

Answer 3

the colorings are diffused. What an astronomer calls a purple megastar is, to easily approximately every physique else, a reddish off-white. we don't see in shade at low gentle stages. have a seem with binoculars. this might rather improve the view of shade. attempt some strongly colored stars, which contain Vega and Arcturus at nightfall, and Aldebaran, Betelgeuse, Capella and Rigel later interior the night.
