What is the use of the Eyedropper Tool in Illustrator?

The Eyedropper Tool in Illustrator is designed to pick colors and styles from existing elements and apply them to other objects. When you select the Eyedropper Tool, you can click on any area or object within your artwork to sample its color, stroke, or even effects. Once you have sampled that property, you can then apply it to any other object or text on your canvas. This tool is particularly useful for maintaining consistency in your color palette and styles throughout your design, allowing for efficient color matching and styling with ease.

For instance, if you have an object that is filled with a specific color and you want to apply that same color to another object, using the Eyedropper Tool allows you to quickly and accurately copy that color rather than needing to remember or look up the color values.
