▶ Panel D15 test of color vision. This is a color marker sorting test. The patient is presented with 15 small color markers that he or she must select and sort according to a fixed blue color marker. Patients with color vision defects will typically confuse certain markers within the color series. The specific color vision defect can be diagnosed from these mistakes.
