The Magic Wand Tool is a selection tool commonly found in graphic design software like Adobe Photoshop. It allows users to select areas of an image based on color similarity. By clicking on a specific color, the tool automatically selects adjacent pixels that match or are similar in color, making it easier to isolate parts of an image for editing. This tool is particularly useful for tasks such as removing backgrounds, changing colors, or applying effects to specific areas. Users can adjust the tool's tolerance level to control how closely the selected colors must match, providing flexibility in the selection process.
