Each row has anchor tiles at each end (grayed). Arrange the scrambled tiles between them in a smooth gradient. Click a tile to select it, then click where you want to place it.
This test is inspired by the Farnsworth-Munsell 100 Hue Test, the gold standard for assessing color vision discrimination. About 1 in 12 men and 1 in 200 women have some form of color vision deficiency.

Our Color Perception test is inspired by the Farnsworth-Munsell 100 Hue Test, developed in 1943 and still used by optometrists, colorists, and industrial quality control specialists worldwide. The original test uses 100 physical color chips that must be arranged in perfect hue order across four hue ranges (red, yellow, green, blue). Our digital adaptation presents gradient segments for arrangement across multiple hue ranges.
Hue discrimination — the ability to detect tiny differences between similar colors — varies enormously between individuals and is partially genetic. Women on average outperform men on fine hue discrimination tasks, likely due to X-chromosome-linked opsin gene variations that allow some women (tetrachromats) to perceive a broader range of color distinctions than standard trichromats. Approximately 12% of men and 0.5% of women have some form of color vision deficiency that reduces hue discrimination.
Screen calibration and ambient lighting significantly affect performance. For the most accurate results, use a calibrated display at full brightness in a well-lit but non-glare environment. Also try the Color Blindness Test to check for specific deficiencies like deuteranopia (red-green) or tritanopia (blue-yellow).
