I figured why not have a background suitable for the heavily light polluted metroplex, so I chose bright orange. The sketch had to be quick because of the clouds were even quicker. With the fast sketch 1/2 done, the clouds rolled over, but their color was strange because of the reflected light pollution. So the overlay of browns and yellows was what I saw, where even clouds get affected by city glow, which, of course, serves little purpose except to render the deep night sky unseeable. Nevertheless, the period was fun, and the sketch is what it is.

I am not in favor of the reason for the orange sky but the sketch is great.

It reminds me of an observation of the Moon during brush fires over South Florida (below). Thank you for sharing it with us all.

It was fun. The orange sheet of paper was the first out of the folder, so I went with it. Think of it as a brand of disfavor for the metroplex's disregard for the night sky.

Well-rendered in either case.

The sketch also brings to mind false color sketching -- a parallel to false color imaging. Once in the past I did the Altai scarp with bright yellows (as white), greens (as mid tone), and blacks for the darkest shadows. It produces a mixture that is equivalent to false color imaging, which is common in astronomy. For those who have not tried it, it actually helps the study of some lunar targets. Somehow the mental re-assignment of colors to a grey-toned moon enhances study and then the results get translated to the sketched moonscape. Would like to see someone else try this. I found it interesting. It also permits interesting assignments of of a wide variety of color sets.
