How it works
Two frames are cycled rapidly. Each frame holds the stable cone at full strength
plus one of the confused pair, with the anomalous shift applied — so only the
ambiguous axis alternates. Above ~25 cycles/sec the visual system fuses them,
reproducing the simultaneous competing-signal ambiguity of the anomalous observer.
Cycling is restricted to the spectral confusion zone; pixels outside it are unchanged.
Drag Cone overlap toward its maximum to push the confused pair toward
full overlap. The two frames become nearly identical in the confusion zone,
rendering those colors indistinguishable — approximating near-dichromacy.
This is an artistic/phenomenological approximation, not a clinically validated
simulation. The "simultaneous percept" framing is inferred from cone-overlap
mechanics and first-person phenomenology.
