A rare genetic mutation allows some individuals to distinguish ten-fold more colours than most humans’ range of ten million but even those possessing the extra retinal cone receptors are not true tetrachromats as the brain, with limited exposure to colours in the wild and the limitations of display screens far less granular than the hundred million upper limits, a seemingly sad, self-handicapping comment on our perception—see also. An experiment conducted on five test subjects hot-wired biological and mental-mapping constraints, however, to stimulate a specific cone, a study named “Oz” for the emerald glasses of the film adaptation, to cause it to encode for a brilliant green hue—appearing like a super-saturated teal for the rest of us—never before experienced, the colour named the above from the binary 010 (for the one targeted photoreceptor, isolated from neighbouring cones) and visible only to those participants for a fleeting moment. Aside from the wonder of surpassing vision, the test also hints at medical and therapeutic applications for degenerative diseases of the eye or for colour blind individuals, rerouting inputs to interpret missing shades.
