    X-Rite Farnsworth-Munsell Dichotomous D-15 Test

    • X-Rite Farnsworth-Munsell Dichotomous D-15 Test

      How it Works

      Farnsworth-Munsell Dichotomous D-15 Test is a two-minute screening for extreme cases of common color vision defects: red (protan), green (deutan) or yellow (tritan) color confusion. You'll need a controlled daylight light source such as an X-Rite Judge II Color Viewing Booth to correctly administer this test.


      You arrange one tray of 15 colored caps in hue order. There's a predetermined sequence for each tray. If you arrange them in the correct order, then you have normal color perception. Anything other than a perfect score indicates a color discrimination problem. But it doesn't mean you can't match color. That's why you need the Farnsworth Munsell 100 Hue Test. It determines the degree of color confusion in addition to screening for these common color vision deficiencies.

      Who uses the Farnsworth-Munsell Dichotomous D-15 Hue Test?

      The Farnsworth-Munsell Dichotomous D-15 Hue Test is used by medical and research facilities to indicate medicinal toxicity and other medical conditions. It's becoming increasingly more popular in high tech industries including safety and security, where good color vision is necessary for ID systems.

      What's the difference between the FM 100 Hue Test and the FM D-15 Test?

      The Farnsworth-Munsell D-15 is only a quick screening to determine whether or not you have a color vision defect. Remember, there are only 15 chips to arrange so if you don't score perfectly, then you have a deficiency.


      On the other hand, the Farnsworth-Munsell 100 Hue Test does more. It not only screens for color vision defects, but also provides a more comprehensive evaluation of the severity of the defect and specifically where the color confusion lies.

      Why the term "dichotomous"?

      It's because the Farnsworth-Munsell D-15 Test was designed to separate people into two groups: normal color vision and everybody else.

    If you pardon the pun colour deficiency is not a black and white issue. I have always been borderline on red green deficiency. With focus and concentration I can see some subtle differences. My grandfather was an Optemetrist and my mother an Optician so the Ishihara couloir dot test was commonly available around our home growing up. I knew my deficiency from early on. It was not until I learned of the Farnsworth D-15 test and the availability to order a set for myself that I finally had a chance to practice sorting colours for myself that I was able to make some progress. For me it was the professional marine industry tests that I was able to pass.
