Who has told that the sky only blue? It happens different color and shades and has a scientific explanation.
> Beam length, naturally, repeatedly increases and therefore at such huge distance almost all short-wave (dark blue-light blue) part of a range dissipates in the atmosphere and doesn't reach the Earth's surface. Reaches us only long waves, yellow-red.
And we need to enjoy the sky of orange color. Personally this color causes only positive emotions in me!
