색상 민감도

Color Sensitivity measures your just-noticeable difference (JND) threshold for hue using an adaptive staircase. It's a research-grounded perceptual threshold task.

Three chips are shown — two identical, one slightly different. Pick the odd one. Three correct in a row makes the difference smaller; a miss makes it larger. Twenty trials.

Your primary score is the final hue threshold (lower is better — a smaller detectable difference means sharper discrimination), estimated against population norms.

Display color gamut and calibration affect thresholds. This is a research-grounded task (Evidence B).
