If you find a suitable object for your presentation but its color does not match the theme of your slides, you can recolor the object directly inside PowerPoint without using any third-party program.
Below is an example of how you can change the color of an object easily inside PowerPoint. I changed a lotus from yellow to blue in just a few clicks. However, this feature is helpful for single-colored objects only. If your objects have multiple colors, filling it with one solid color may make it look strange. Transparent parts in the objects remain unaffected.
1. Launch PowerPoint, and open the presentation that contains the object whose color you want to change.
2. Navigate to the desired slide, select the object, and click the Format tab, which is the option farthest to the right on the ribbon.
3. In the Format tab, under the Adjust section, choose Color. You will then see a list of predefined colors from which you can chose. Move your mouse over the option to preview the change on your object in real time. If you cannot find the color you want in the list, choose More Variations at the bottom of the menu.
4. Under the More Variations menu, you can choose one of the provided theme colors or click More Colors and set your own color. If you already have an object that contains your desired color, you can use the Eyedropper feature to get the color code from it quickly.
5. Please note that this is destructive editing. This means that you may not be able to revert back to the object’s original color, unless you use the Undo function. If you still have a copy of the object on the hard drive, re-inserting it into your presentation will help, but you may have to re-add additional effects to it.
