What is the purpose of the `fill(color)` method in CodeHS?

The fill(color) method in CodeHS is designed to fill a shape with a specified color. When this method is called and provided with a color parameter, it determines the interior color that will be used for rendering shapes that are drawn afterward. This is particularly useful when creating visual elements, as it allows for the customization of how shapes appear on the canvas.

Other options relate to different aspects of graphical output. For instance, outlining shapes involves a different method that focuses on setting a stroke color rather than filling it. Setting the background color of the canvas pertains to a separate function specific to configuring the overall environment, while changing the text color deals with text rendering settings. Therefore, the fill(color) method is distinct in its functionality, specifically targeting the interior of shapes.
