In a UI design system, what is the purpose of brand tokens?

• A. They store user credentials for access control.
• B. They optimize database queries for performance.
• C. They define visual attributes like color, typography, and spacing that reflect the brand.
• D. They track project milestones.

Answer: (C)

Brand tokens capture the brand’s visual identity inside a design system by turning its visual decisions into reusable values. They define the brand’s colors, typography attributes, and spacing scales so UI components can consistently reflect the brand across screens and platforms. Because these values live in one place, updating the brand look is as simple as changing the token definitions, and those changes automatically propagate to all components. This approach also helps with accessibility by maintaining coherent contrast and typographic choices. The other options aren’t about visual identity in a design system—storing user credentials is a security task, optimizing database queries is about performance, and tracking milestones is a project-management activity.
