Drawing in colour

In the split second after a model strikes a pose, when you know you will only have minutes, to tens of minutes to say something, grabbing colours can be almost arbitrary. I usually start with three colours and then choose the next few to get a range of values and to complement my first choices. Sometimes the model is really quick and I barely have time to choose the first few and rely on what is in my hand to begin again.

I am starting to draw in order to paint, although in that split second I don't think I'm thinking about anything like that.  I am just trying to get the shapes in the rectangle to work together.

 Not all poses or choices work, but a piece of something unsuccessful may inform something later.
