How can I create a beautiful gradient effect on my canvas using a fan brush?

To create a beautiful gradient effect on your canvas using a fan brush, start by selecting two or more colors that blend well together. Load the fan brush with the lighter color first and apply it to the canvas in a sweeping motion. Then, gradually introduce the darker color by loading the brush with a mix of both colors and blending them together on the canvas using light strokes. Continue this process until you achieve the desired gradient effect.
