I know that you do the colors of the sky by real calculations, but as a resident of the Moscow region I can say (and not only on my own behalf, but from familiar photographers and sky lovers) that the evening sky in winter certainly does not look like in the screenshot. Yes, it's VIP, but I just simply suggest first of all to listen to the opinions of other people (what you don't like how it turned out before when I've been writing about the color of the sky) or to see the SKY in person!
NO camera will not give real colors, and the eyes of all people see everything differently, but the truth will remain true. The evening sky in winter doesn't look like the sky from Mars (sorry if it's hard for you to listen). It looks exactly like the pictures above.
P.S. I do not want to hear about the types of cameras and the characteristics of the photoreceptor of the eye. It's your job to do what you want, but I don't understand why you think the blue-pistachio-gray color of the sky is real.This sky is, but not without clouds and haze.The clean clear the sky blue (here is here already debate - foolish).
