I'm painting this scene twice. Same objects setup in my windowsill, but a different background for the two paintings. The objects are all blue, blue-green, or blue-violet colors. The background on the first painting has a lot of reds, so it will be about color contrasts. The background on the second painting is mostly greens, so it will be about color harmony.
The light is coming from outside, so the outside has to be all bright hi key, no dark shadows, and the objects in the window should be slightly darker, with some dark shadows.
"Green" painting. I need to brighten the window scene tremendously.
