For this example, I only used solid color puddle paints. You can absolutely pour from a cup as a color.
STEP 1: Between each drop of solid color you place onto the dry canvas is a layer of black puddle paint. For example: red, black, orange, black.
STEP 2: After dropping two colors and two layers of black, pick up the canvas and tilt the paint puddle side to side a few rotations.
STEP 3: Then, add two more colors and two more layers of black and repeat step 2 until the entire canvas is covered.
