RGBY-K3L: A Corrective Addendum on Binary–Trit–Spectral Concordance and the Proposal of Spectral–Acidic Memory Cells

This paper provides a corrective addendum to the 4CH-K3L framework by redefining the binary–trit–spectral mapping. We propose an RGBY scheme in which the logical states N, P, A, and X are represented by Blue, Green, Red, and Yellow, respectively. This correction shows that the ambiguity state X=11 is not merely a binary maximum but a natural superposition of A and P, corresponding optically to the blending of red and green into yellow. We also introduce out-of-alphabet erasure/reset channels (UV and IR) to prevent symbol overlap, and propose a fuzzy decoding model in the CIE-Lab space to ensure stability. This addendum demonstrates that aligning bits, trits, and colors strengthens the K3L paradigm and enables practical pathways toward spectral–acidic memory cells and high-throughput neuro-optical processors.
