How do you change the colors of a diagram to colored fill accent 2?

To change the colors of a diagram to "Colored Fill Accent 2," using the change colors button is the appropriate method. This feature allows users to easily access different color variations for their SmartArt diagrams without needing to manually adjust each individual shape. The change colors button is specifically designed for this purpose and offers quick access to predefined color schemes that can instantly apply to the entire diagram, ensuring a cohesive look that aligns with the desired design style.

When you select the change colors button, you'll see a list of color options, including "Colored Fill Accent 2." Choosing this option will alter the fill color of the shapes in the diagram while maintaining their original structure and layout. This is ideal for users who want to enhance the visual appeal of their diagrams with minimal effort.

The other methods described do not effectively achieve the goal of applying a specific accent color scheme to the entire diagram. For instance, using the SmartArt tools might allow for some color adjustments, but it does not directly lead to the "Colored Fill Accent 2" option. Similarly, the shape fill button adjusts the color of individual shapes rather than applying a cohesive scheme to the whole diagram, and accessing the format tab for diagram colors might not offer the exact predefined colors you’re looking for,
