Final Answer:
Color swatches in InDesign serve as predefined color references that maintain consistency throughout a document. They streamline the design process by allowing users to apply and manage colors efficiently.
Step-by-step explanation:
Color swatches in InDesign play a crucial role in maintaining design consistency. When a color is chosen and saved as a swatch, it becomes a reference point throughout the document. This is particularly useful for branding or projects where a specific color palette must be adhered to.
By using color swatches, designers can easily apply and update colors across various elements within the document, ensuring a harmonious and cohesive look. This not only saves time but also minimizes the risk of inconsistencies that may arise when manually inputting color values.
