When you pour a background for a painting, you may not know what you're going to do with it - what it will eventually become. I don't often "see" what's there when I see an abstracted bunch of colors and shapes like some people do. This one isn't talking to me. I just used the 3 primaries, yellow, blue, red; without any preconceived notion of what I might draw over it.
What do you see?
I flipped it to see if it made more sense to me like this. I think it seems more like a landscape now, but I still don't "see" anything.
It's an odd trick of the eyes and the camera that the same Scarlet Lake color looks cool against the blue and warm against the green.
