Recently I've found myself using this palette a lot. Starting with a black background definitely gives a lot of depth. These are repurposed canvases, so I scratched through the black paint and the colours come through, although they don't show up so well in photos.
Sometimes it takes me a while to work out what I am painting about. This is about menopause. Not surprising, really, as it is a big transition.
I think these pieces are finished, but I'll give it a couple of weeks just to be sure.
Do you know what you're art is about before or after it is finished?
