Design tokens give names to reusable visual decisions: colors, spacing, typography, radii, shadows, motion, and more. They can connect design and code, make themes easier to manage, and reduce inconsistency. They can also become an abstract naming exercise that consumes more time than it saves.
Begin with values that are already repeated and likely to change together. Brand colors, text colors, surface colors, core spacing steps, typography styles, and common radii are a practical starting point. Avoid creating a token for every unique number before understanding whether it represents a reusable decision.
Separate primitive values from semantic roles when the scale justifies it. A primitive might be blue-600; a semantic token might be color-action-primary. Components should usually consume semantic roles so that a theme or brand update does not require changing each component individually.
Names should describe purpose rather than appearance. text-muted survives a palette change better than gray-text. Keep the vocabulary small and documented. If contributors cannot predict a token’s name, they will create alternatives or bypass the system.
Do not force all variation into global tokens. A one-off campaign illustration or experimental page may legitimately use local values. Tokenization is most valuable for decisions that require consistency across multiple components and surfaces.
Governance can remain lightweight. Define who can add tokens, what problem a new token must solve, and how deprecated values are removed. Review the system during real feature work rather than designing a theoretical architecture upfront.
The best token system is not the most comprehensive. It is the smallest system that makes common changes safer, communicates intent clearly, and stays understandable to both designers and developers.
