Hybrid Color Vision Screening

Complete a hybrid battery with 20 motion trials, 24 pseudoisochromatic plates, 12 odd-one-out checks, and 4 compact sorting blocks for a richer online color-vision screening result.

Completed 0/60

This is a hybrid online screening battery, not a medical diagnosis. Use steady white light, normal brightness, and avoid strong filters or warm night modes while completing the full set.

Task 1

CAD-style motionRed axis

Motion 1/20: focus on the central square and judge which diagonal direction the chromatic check target moves toward.

This motion trial leans more on the red axis, with the target embedded in dynamic luminance noise.

Hold the central fixation point and judge which diagonal path the chromatic check target takes across the square field.

The battery combines cues from several public methods, so do not over-read a single hard task. Watch whether the overall pattern repeats on the same axis.
