Wavelength Discrimination Threshold
Adjust the slider until the color on the right is just noticeably different from the reference.
Empirical vs. Theoretical Qualia Output
Plotting your 1st-person subjective discrimination against the 3rd-person DNA Fisher Information Metric.
The Hard Problem Resolved
In philosophy of mind, the "Hard Problem" asks how physical wavelengths become qualitative inner experience. This experiment maps that translation perfectly. You just measured your Just Noticeable Difference (JND, Δλ) across the spectrum.
The theoretical cyan curve represents the inverse square root of the Fisher Information Metric (1/√IF(λ)) derived mathematically from the overlap of human OPN1SW, OPN1MW, and OPN1LW (Blue, Green, Red) cone opsin genes. Notice how your subjective ability to distinguish colors peaks (the lowest JND thresholds) precisely at ~490 nm (Cyan) and ~580 nm (Yellow). Qualia is simply the interior, 1st-person experience of 3rd-person genetic geometry.
