NebulaKit provides only light and dark themes because these backgrounds deliver the most reliable contrast, readability and accessibility across all components. Mid-tone or custom backgrounds can disrupt color balance and intent-based styling, leading to inconsistent visual results. By focusing on absolute light and dark surfaces, NebulaKit ensures predictable visuals and stable accessibility in every project.

In NebulaKit, color selects a palette, but intent defines how that color is applied. Without intent, components remain neutral. This avoids hidden semantic defaults and keeps visual emphasis explicit and predictable.
