Test your color vision with our online Farnsworth-Munsell 100 Hue test. Identify color blindness types including protanopia, deuteranopia, and tritanopia.
This tool was born from a moment of high-stakes doubt when our founder realized his eyes might be lying to him. For many, this realization doesn't happen in a doctor's office; for him, it was in a power substation, staring at an industrial relay and being unable to tell if the indicator was red, green, or a confusing mix of both. Whether you are an engineer in the field or a driver at a traffic light, the sudden question of "Am I color blind?" is unsettling. We built this Farnsworth-Munsell 100 Hue Test because in technical trades, color perception isn’t just an aesthetic choice, it’s a safety requirement.
This color blindness checker is designed for those who need more than a simple "pass/fail" screening. By challenging you to arrange tiles across the full visible spectrum, our engine pinpoints exactly where your color vision deficiency lies whether it’s Protanopia, Deuteranopia, or Tritanopia. By providing a detailed Total Error Score, we give you the data needed to understand your visual baseline before a confusing LED or a color-coded wire leads to a critical misinterpretation.
Expert Accuracy Note: In industrial environments, "simultaneous" color signals or dim lighting can trick even perfect vision. To get the most reliable results from this Farnsworth 100 hue test, ensure your screen is calibrated to a neutral color profile and your environment is free from colored reflections. While this tool offers a high-fidelity look at your vision, a formal diagnosis for occupational certification should always be confirmed by an optometrist using a physical Munsell kit.
Farnsworth 100 hue test can identify the three main types of color vision deficiency: Protanopia (red-blind), Deuteranopia (green-blind), and Tritanopia (blue-blind), as well as their partial forms (anomalous trichromacy).
While our online test provides a good indication of color vision deficiency, screen calibration and lighting conditions can affect results. For official diagnosis, visit an optometrist for controlled-environment testing.
Color vision deficiency affects approximately 8% of men and 0.5% of women globally. The most common form is red-green color blindness (deuteranomaly), affecting about 5% of males.
