I was just wondering where the heck is Astro Boy on this. Same scattering vantage point and conditions that make the sky blue and sunsets red?

It's selecting wavelengths, but the color seen is based on the amount of atmosphere passed through, or the angles of incidence?

This one confused me in astronomy. I can see sunset clouds, overhead and at the horizon, being red from scattered radiation, but when the sun disc at the horizon sets red-orange it seems as though the red light must be coming from there unscattered, in parallel rays, and the blue scattered or filturd or suppressed. (Ignoring air pollution - it still happens in clean air.)

So I can see the overhead and horizon sky being pink from volcanic particles scattering the red, and leaving the direct rays of the moonlight "filtered" blue, "cleaned" blue, but why is the setting sun not blue if the red is being scattered?
