I start my painting process by putting every paint colour I have, other than black, onto the palette. I cover canvas after canvas by blending colours while rotating the canvas as I go. I do multiple layers like this, making marks on the canvas and the colour choices intuitively happen.  I am always in the middle of several paintings at once, I switch between abstract and more realistic art as I can't focus on one thing for too long. My artwork organically matures the more layers I apply until I sense a piece is finished.
