The Farnsworth D-15 is an Arrangement Test where an individual must arrange 15 colored tiles that form a gradient between two colors. This is a very common test for diagnosing Color Vision Deficiency. It is also considered easier to pass than the Ishihara test, as it designates only 4.6% of males as CVD compared with the Ishihara test at 9.3% (Jordinson + Minshall 1959).
