Atmosphere Tests

I’ve done some initial color tests for the atmosphere and terrain. I wanted to see what a yellow atmosphere with a blue star would look like and how the atmospheric scattering would effect red colored plant life. The sunlight has a slight bluish color (rather then pure white or yellow/red) and the “red sky” effect is blue and the “blue sky” color is now yellow. When using semi-physically based rendering methods, this naturally generates interesting gradients and sunsets.
