Farnsworth D-15 dichotomous test is a colour blindness test, is a quick and convenient test for routine clinical use to differentiate between protan (Figure 4), deutan (Figure 5) and tritan (Figure 6) colour vision deficiencies and calculate an approximate severity of colour blindness.

Two tests are needed; one test identifies redgreen deficiency and classifies protan and deutan deficiency, while the second test is used to estimate the severity and identify significant tritan deficiency.

The test identifies protan, deutan and tritan defects (the last of which cannot be detected by the Ishihara test), and has the added advantage of allowing the parent to understand what colour confusions the child experiences.
Assessing visual function in children II: young children's vision Part 4 C-18705 O/D
It is well established that retinal conditions, such as in diabetes and various macular conditions, may cause confusions between blue and other stimuli as well as protan and deutan manifestations.
