Default Pink clouds in the sky

There are times at sunrise and sunset when clouds, and the steam from
the local power plant, appear pink. I have found it interesting to try to
predict it. Obviously, the local sunrise and sunset times are involved, but
there has to be enough red light available in sky to be reflected from the
clouds or the steam, which leads to such things as the two forms or
light-scattering that color the sky, and to a better understanding of how
the atmosphere acts as a lens.

The steam from the power plant is to the East of me. At sunset, any
clouds to East are at a much higher altitude. I initially expected the
steam clouds to be pink at the same time as the clouds in that same part of
the sky. It should have been more obvious that the steam clouds, at such a
low altitude, would be pink at nearly the same time as clouds to the North
and South. i.e. the time when red light is available to make them pink is
nearly the time when clouds show pink along my "meridian". I expect there
are more such things to be learned, that I haven't yet considered.


Thanks in advance,
