Once the scales were defined and structured, the next step was to determine which tonal steps would be activated in the initial design system implementation. Rather than exposing the entire range, a curated subset of intervals was selected to support core interface use cases (e.g., surfaces, text, borders, states), ensuring clarity and reducing unnecessary complexity.

The non-activated intervals remain intentionally preserved within the primitive layer. These unused steps play a strategic role in maintaining scalability, enabling future expansion, theming flexibility, and the introduction of new semantic tokens without requiring structural refactoring.

The tonal ramps themselves remain identical across Light and Dark modes. The distinction lies in how intervals are mapped at the semantic layer. For example, the surface token in Light mode corresponds to Gray50 (#F7F7F7), while its Dark mode counterpart maps to Gray1100 (#1A1A1A). This approach ensures consistency at the primitive level while enabling contextual adaptation through semantic reassignment.
