Every canvas is a journey all its own.
You have to know how to use the accident, how to recognise it, how to control it, and ways to eliminate it so that the whole surface looks felt and born all at once.
A really good picture looks as if it's happened at once. It's an immediate image.
I'd rather risk an ugly surprise than rely on things I know I can do.
I don't start with a color order, but find the colors as I go.
There are no rules. Let the picture lead you where it must go.
