Standard online color tests often give you a simple pass or fail score. The Color Blind Test on BlindnessTest takes things a step further by evaluating your vision channel by channel.

Ever wondered how classic color vision dot plates actually work? The Ishihara test is one of the most famous red-green vision screening methods in the world.

This online version follows the complete Kanehara 38-plate structure. It includes standard screening plates with hidden digits, classification plates for mild patterns, and a finger or mouse line-tracing option for anyone who prefers not to read numbers.

Do you have a sharp eye for subtle color shifts? The Farnsworth-Munsell 100 Hue Test checks how accurately you can arrange similar shades across the color spectrum.

Unlike basic pass or fail plate tests, this tool asks you to drag and drop colored caps into a smooth rainbow order. You can take a fast 40-cap quick test or the full 85-cap clinical run to get an instant total error score and a visual polar diagram.

In clinical settings, eye specialists use an anomaloscope to check color vision by having patients match split light sources. Now you can try that same color matching concept right in your web browser.

This online tool presents seven split color pairs alongside a simple brightness slider. You adjust the slider until both sides match or select match not possible if they do not look identical. You can run tests along either a red-green axis or a blue-yellow tritan axis.

Try your hand at matching color pairs on the Anomaloscope Test Page: https://www.blindnesstest.com/anomaloscope-test/

When you want more than a simple pass or fail mark, threshold testing measures the exact smallest color difference your eyes can pick up along specific visual axes.

This Cambridge-style test places a hidden Landolt C ring inside a field of noise dots. As you identify which way the gap points, an adaptive staircase adjusts the contrast to estimate your precise threshold along protan, deutan, and tritan confusion lines.

How quickly and accurately can you identify signal lights under timed conditions? The Farnsworth Lantern Test was originally built for aviation, maritime, and railway safety checks where fast light identification is essential.

This online simulator flashes stacked pairs of red, green, and yellow signal lights for brief intervals. You name top and bottom colors across 9 or 18 pairs to test your practical signal recognition skills under pressure.
