The Inverted Spectrum

The Inverted Spectrum is a thought experiment in philosophy that raises questions about perception and consciousness. It imagines a scenario where two people see colors differently—one perceives red as blue and vice versa—but they both use color terms correctly. This challenges our understanding of subjective experiences: if their behaviors and language are the same, can we truly know what another person experiences? It highlights the difficulty of comparing subjective experiences and suggests that even with shared language, individual perceptions might be fundamentally different. This has implications for discussions about consciousness, identity, and the nature of reality.
