The method of double-clicking the image and selecting picture styles under the format tab is the correct approach for adding effects such as a color border around images in PowerPoint. This feature provides users with a convenient way to enhance images directly within the application without needing to use external tools.

By accessing the format tab, users can explore various style options, including borders, shadows, and other effects, allowing for quick customization. Picture styles offer a variety of pre-defined options, making it easy to achieve a polished and professional look for presentations. This integrated functionality streamlines the process, making it accessible for users of all skill levels.

The other options, while they may seem plausible, do not provide the same level of direct image editing ease within PowerPoint as utilizing the format tab does. Using an external image editor would require additional steps and software, while the design tab focuses on overall slide aesthetics rather than individual image effects. The insert tab and SmartArt are intended for adding new graphic elements rather than modifying existing images. Thus, utilizing the format tab is not only the correct method but also the most efficient for enhancing images in PowerPoint.
