I have just started with the joys of creating blacks. I sincerely thought that if I didn't have a tube of a color I couldn't do a damn thing. I have found that I like dark skies to have a touch of deep blue or purple. The dark skies after sunset and just before sunrise has a bit of red or orange red.
What I miss most is when I lived in the city I could lay on the grass and stare at the night skies forever. The stars moved and would become brighter or less so. Here in the city there are no stars and I find that to be so very sad. Sunrise and sunset are more vibrant because of more pollution.
Also in the night skies, the position of the moon and its phases. Some nights are very bright and others are very dark. Just because it hasn't been a common thing for artists to make people aware of night sky differences doesn't mean you cannot be the first!
Do a series where all the land markers are the exact same but appear so differently under the changing night skies.
Of course I cannot do it but I can see it and encourage others!
