What is a magic fill tool in coloring apps?

The magic fill tool, also known as the paint bucket tool in some apps, is a feature that allows users to quickly fill an enclosed area with color. When you tap an area with this tool, it automatically fills that section with your selected color, detecting the boundaries of the shape. This tool is particularly useful for coloring large areas quickly or for achieving a clean, uniform look. Some advanced versions of this tool can detect and avoid filling small gaps in the lines, making it more forgiving to use. The magic fill tool is a time-saving feature that can significantly speed up the coloring process.
