I call these pictures chromodynamic art as I'm using pressurized air to shoot acrylic paint against the canvas. I'm using two different types of "paint guns": One works as kind of a big squirt gun, the other one has a thick barrel with a valve at the end. When the valve is opened, the paint in the barrel is nebulized and shot against the canvas.
Below pictures painted with the first type of paint gun:
