It is an arrangement or hue discrimination color blindness test designed for classification. It separates patients into one of two categories: i. Medium and Strongly color deficient or ii. Color normal and Mildly color defective. It is achieved through the arrangement of 15 detailed colored discs. It makes the assessment reasonably smooth and a non-perfect score points to a substantial color deficiency. It's the older version of the renowned Farnsworth–Munsell 100 Hue Color Vision Test.
