In our design system, users can apply color to various components of an app in different ways. Our approach is to provide a set of predefined color themes for users to choose from. These themes include a range of colors that have been carefully chosen to work well together and create a cohesive and visually pleasing design. Users can then select a theme that best matches their preferences or the branding of their app.

Users can also have the option to fully customize their app's color scheme by choosing individual colors for different components. This can include colors for the background, text, buttons, and other elements of the interface. This allows users to create a more unique and personalized design, and can be especially useful for apps that need to match a specific brand or color scheme.
