PowerPoint’s fill, line, and effect attributes enable you to customize the look of shapes and other slide objects in your presentation. However, it may take ages to get that perfect color coordination and even after spending time the final look may not match the Theme of the presentation. So as an awesome alternative to end up with a coordinated color combination for the slide objects in your presentation, you can use Shape Styles. Shape Styles are a collection of prebuilt styles housed within a gallery of the same name. These styles are all Theme-specific, so if the presentation Theme is changed – you’ll end up with new Shape Styles.
