Which feature is used to change the fill color of a shape using an Eyedropper?

The feature that allows you to change the fill color of a shape using an Eyedropper is the Shape Fill menu. This option provides quick access to fill colors, gradients, and patterns for shapes in PowerPoint. The Eyedropper tool specifically enables users to capture and apply a color from anywhere in the presentation or from other applications, making it a powerful tool for ensuring color consistency and enhancing visual elements.

While the Format Shape options provide a more detailed interface for customizing shapes, including size, rotation, and fill effects, the Eyedropper is directly accessible from the Shape Fill menu. This makes it the most efficient option for quickly filling shapes with colors from existing elements. The Draw menu typically focuses on drawing tools rather than shape formatting, and the Color Options menu may not specifically provide the Eyedropper functionality charged with fill colors. Thus, the Shape Fill menu is the most relevant feature for this specific task in PowerPoint.
