Typically, you'll choose the darker of the two colors you're using. Paint broad strokes across the canvas, covering as much of it as you want with the color. Let the base coat dry completely.  For example, if you want to paint a blended sky, paint a solid medium blue background and let it dry completely. One nice thing about this method is you don't have to work as quickly. The base coat doesn't need to be completely dry before you continue, but it should be mostly dry. That way, you can easily add another color on top of the base coat. If the base coat is thin enough, it should dry quickly, within 5-10 minutes.
