Which panel is used to update and reuse colors across multiple documents?

The Swatches panel is the ideal tool for updating and reusing colors across multiple documents in Adobe Animate. This panel enables users to create a palette of colors that can be saved and organized for easy access. When a swatch is modified or updated, all instances of that swatch in your documents are updated simultaneously, ensuring consistency in design and color usage. This feature is particularly useful when working on complex projects or collaborative environments where color consistency is important.

While the other panels have specific functionalities, they do not serve the purpose of color management. The Actions panel is used for scripting and automating tasks within your animations, the Component panel is focused on managing components and instances, and the Timeline panel is designed for organizing the timing and order of your animations. Each of these panels plays a vital role in the animation workflow but does not provide the same color management capabilities as the Swatches panel.
