Here is a glimpse of one of my paintings approximately half finished. The glaring orange along the bottom is the initial base layer of every painting I do. I like to have the dramatic color underneath because is seems to give the final coloring in my paintings a bit more ‘depth’. Blue isn’t just blue, there is a little more dimension to it. It also works well, if I want to have a bit more warmth in a certain part of my painting, I allow a bit of the orange from my under-layer to peak through.
