Which feature allows you to create a consistent color palette based on existing artwork?

The Color Guide panel is designed specifically to help you create a consistent color palette by providing various color combinations based on the colors present in your existing artwork. This feature enables you to explore harmonious color relationships and generate tints, shades, and variations that complement your design. By selecting a color from your artwork, the Color Guide panel can suggest colors that work well together, making it easier to maintain a cohesive look throughout your project.

The other options, while useful in their own contexts, do not serve the same purpose as the Color Guide panel. The Color Picker allows for selecting specific colors, but does not generate palettes or suggest related colors. The Gradient Tool is used for creating gradient effects rather than establishing color harmony. The Mixing Panel is generally focused on combining colors but lacks the functionality to propose a broader palette based on the artwork. Thus, the Color Guide panel is the ideal tool for creating a consistent color palette.
