Calibrate
One baseline round each for Hue, Saturation, and Brightness.
3-channel calibration · adaptive route · local profile
A nine-level color-memory run that pays attention to how you play. Calibrate all three HSB channels, then let your weakest skill choose what comes next.
Memorize a color, rebuild it with HSB sliders, and watch the route shift toward Hue, Saturation, or Brightness. The stronger you perform, the shorter and subtler the next sample becomes.

One baseline round each for Hue, Saturation, and Brightness.
The lowest live channel becomes the next focus; recent accuracy sets difficulty.

The first three rounds calibrate Hue, Saturation, and Brightness. The remaining six rounds target your lowest current channel and adjust difficulty from your recent scores.
It is a playful 60–140 session score derived from nine color-memory matches. It is not a standardized intelligence, medical, vision, or psychological assessment.

Yes. The result separates Hue, Saturation, and Brightness accuracy and recommends the lowest channel for your next run.
