What is the main function of the Live Paint Bucket Tool?

The Live Paint Bucket Tool's primary function is to easily fill areas of a Live Paint object with color. This tool allows users to select and fill regions of artwork that have been converted into a Live Paint group, which can include overlapping shapes or areas that are not fully enclosed. When using the Live Paint Bucket Tool, you can click within the different sections of the artwork to apply colors, making it a user-friendly option for coloring complex illustrations quickly.

This tool effectively enhances the workflow for artists and designers by providing a way to intuitively apply colors without the need for manual selection of paths or shapes. The flexibility it offers, such as the ability to fill open shapes and add multiple colors to various parts of an illustration, makes it invaluable for detailed work and creative expression in vector art.
