Hue Ordering Test
A simplified adaptation of the Farnsworth-Munsell 100 Hue Test. Arrange color chips in continuous hue order — the number of errors reveals your color discrimination precision. Top scorers have near-tetrachromatic color sensitivity.
Hue Ordering Test
Color chips appear in scrambled order. Arrange them in a smooth gradient from left to right. Tap a chip to select it, then tap where it should go.
🔒 First and last chips are fixed anchors

01 /How to Play
- Focus on the center of the screen.
- When a visual stimulus appears, click or tap as fast as possible.
- Complete 10 rounds — your average visual reaction time is your score.
- Your reaction time is compared to population norms by age group.
- Lower milliseconds = younger visual processing age.
02 /The Science
Visual reaction time integrates retinal processing speed, optic nerve conduction velocity, and primary visual cortex response time. Unlike simple reaction time tests, this protocol uses specific visual stimulus parameters to isolate the visual processing component. Research shows visual RT increases approximately 1ms per year from age 25, accelerating after 60. The test provides an estimate of your visual processing age relative to population norms.
03 /Pro Tips
- Fixate on the center of the screen — peripheral detection is slower.
- Blink before each trial to refresh your visual field.
- Avoid caffeine deficit — visual processing speed is sensitive to arousal state.
- Screen refresh rate matters — 60Hz+ displays give most accurate results.
- Test in consistent lighting conditions for repeatable results.
