Thank you everyone for your comments and suggestions.
Scottyarthur, Gamblin Radiant Yellow? Could you translate that into pastel Talk
Believe me, that poor paper has tried all the yellows I have!
I did make some tiny changes: I added speckles of orange and white to the tree and I used a "warmer yellow" right below the sunlit tree branches. This is really the area I wanted to emphasize. I cannot change the color of the grass in the foreground simply because the paper cannot take any more pastel. Considering how I have abused this paper, it's amazing it still holds pastel!
I do not know if the changes show in this pic:
Maybe it's just me, but although I have a fairly good idea about cool and warm colors, and know these terms are relative to other colors in the painting, I get very confused when it comes to greens. I wonder if my coming from the tropics has something to do with this. After all, most of the color theories are from northern latitudes. I would like to hear what you think about this. (Carol, Charlie? )
Pam, Donna, Yes, it's late in the day, about 8 PM.
The pic is from where I live, in Central NY. We rarely get over 90F in the summer so the grass stays green till winter. When I visit friends in Maryland in late summer, I'm so aware of the color change: It seems to me that just south of PA it gets drier, but even that "pale, washout" yellow is beautiful and gives a feeling of warmth!
Susan, pastellar, you were right on. Why call attention to that kind of light? I'll like Evening Light
very much. Pastellar, thanks for suggesting it.
bnoonan, This is actually a second version and a very different one from the first. The first one was darker and softer, I was trying to convey the feeling of almost evening. I sold it, but unfortunately, I do not have good pics of it.
I'm sorry if I do not mention each of you, but I really, really appreciate your comments. Thanks again,
