The “Eyedropper” tool in PowerPoint is a feature that allows you to extract and match colors from shapes, images, infographics, videos, or any other element inside or outside your presentation.
Make sure to select only those shapes to which you intend to apply the color. Don’t select the object that has the intended color.
It is the first option to the right of the “Drawing” section, which is located in the “Home” tab. This will open a drop-down menu.
After you have opened the drop-down menu, select the “Eyedropper” option which is the 4th option from the bottom in that dropdown menu.
After you have selected the “Eyedropper” option, the cursor of your computer will change to the icon of a small eyedropper.
To apply the color, simply click on the object on the slide that contains the intended color and the objects will change colors accordingly.
