Supports the most efficient color deficiency screening. Six plates (screening series) present the most difficult yellow, blue, red, and green colors and separate Normals from Defectives. Subsequent 14 plates diagnose as to the extent (mild, medium or strong) and type of defect (protan, deutan, tritan).
