Color Hue Test
A row of colors that all share the same brightness is shuffled. Tap two tiles to swap them and arrange every tile from the lowest hue to the highest. Each level adds more tiles — how far can your eyes take you?
Tap two tiles to swap them, then press Check.

About the Color Hue Test
This test checks how well you can tell close shades apart. Every tile has the same saturation and lightness, so the only difference is hue — the position on the color wheel. Arranging them in order is a measure of color discrimination, similar to the classic hue arrangement tests.
Tap one tile to select it, then tap another to swap the two. Press Check order when you think the row is sorted from the smallest hue to the largest. Sorting correctly moves you to the next level with more tiles; a wrong check costs one of your three lives. The test ends when all lives are gone.
About
The Color Hue Test measures your ability to discriminate fine differences in hue by asking you to reorder a shuffled sequence of color tiles into a smooth gradient. Each tile represents a narrow step along the visible spectrum, and the task requires you to compare adjacent tiles and decide which has a slightly longer or shorter wavelength. The test runs entirely in the browser with no time limit, letting you focus on perceptual accuracy rather than speed.
How your result is scored
Your result is calculated by counting how many tiles are out of their correct spectral position after you submit the arrangement; fewer misplaced tiles produce a lower error score. A low error score indicates strong hue discrimination, while a higher score suggests difficulty distinguishing closely spaced colors. Because lighting, display calibration, and fatigue can affect performance, the score should be treated as a casual benchmark rather than a clinical assessment of color vision.
Tips to improve
- Start by locating the obvious ends of the spectrum, then work inward.
- Compare each tile side by side under consistent ambient light.
- Use a calibrated monitor or device with good color reproduction.
- Take short breaks if your eyes feel strained during long sessions.

Frequently asked questions
- Does this test diagnose color blindness?
- No, it is a casual screening tool and cannot replace a professional clinical evaluation.
- Why do my results change on different screens?
- Display gamut, brightness, and color temperature all alter how hues appear, affecting sorting accuracy.
- Is there a time limit?
- The test has no timer; you can rearrange tiles until you are satisfied with the order.
