Putting layers of opaque paint over an already layered board substrate, my preferred surface for collaging, scraping, sanding back and generally degrading the surface. Many colours applied at random, new and varied colours I would not normally try. Perhaps it could be harmonised with a glaze, but what to choose.
This must be the one you mentioned recently. Intriguing because at first glance it seems like a melange. Then when I pull back, I realise that I recognise the easel and there are people in the room looking out the windows. Apparently this is my colour pallette too.
