This is not merely a matter of the camera and software. I see the color in real life, which is why I bothered to take this photo.

Most folks might not notice the green (or cyan, depending on circumstances), as it is very bright and nearly gray. My point is that the transition from orange to blue goes via yellow and green, rather than via purple. Might be different under different atmospheric conditions.


This is refraction caused by the water droplets in the air. Starting from the darkest top it is violet, then cyan, green, yellow, orange, and red. I would think that any gray you see are saltiating particles, for example how the clouds have a gray color sometimes, and this is most likely because you are viewing the atmosphere at some specific angle where this shows up. It is all the typical and invariable spectrum (the natural one not the paint one), which is what the human eye sees (dogs/birds etc see different colors), due to rods and cones if not colorblind, and are of specific radiation wavelengths 400-700 nanometers.

Re: yellow with no green

Take a yellow object and dim the lights low enough and it will appear green. True story. Its one of those things where your mind keeps telling you "its yellow" but really you should be mixing green.

Its worth to do a few studies of a yellow ball in different levels of light.

Re: yellow with no green

I just came across this interesting article on modelling the sequence of colours in the sky.
