The yellow orange you see is what is called toning the canvas. Giving the whole canvas one color besides the typical white that it comes. Usually using a complimentary color from the main colors that will be used in the piece helps unify the painting and give it richness and depth. This is one of my bigger pieces I've done and so this first go around is what I call blocking in. Basically making the shapes distinct and tones dialed in. Then I will go back over it with more precise colors and details..
There is a very special thing I will be adding in several days that will bring more sense (at least in my mind) to the whole thing. I like to get the basics in and collage items in. Just my preference of how I do paintings.
What do you think it is now?
