Robust individual alignment of color qualia structures: toward a structure-based taxonomy of divergent color experiences

A theoretical framework is proposed for aligning color qualia—the subjective experience of color—across individuals by focusing on structural relationships rather than shared labels. The authors argue that even if two people have systematically different color experiences (e.g., red-green inversion), the internal relations among colors (e.g., similarity, contrast, ordering) can be robustly matched. This structure-based approach suggests a taxonomy of divergent color experiences that respects individual differences while maintaining a common framework for scientific study. The paper outlines a formal method for mapping qualia structures and discusses implications for consciousness research and philosophy of mind.
