- Hello. My evil twin(tm) is a green-blind deuteranomal.
- Due to the presence of an annoying little recessive gene
- on his X-chromosome, the spectral sensitivity of his
- middle cones peak at a different wavelength of light
- than a "normal" individual. Thus, greens look different
- to him, or not like "green" at all...
-
- He enjoys both hiking in the wilderness and psychadelics,
- especially simutaneously. In the wilderness, it's often
- useful to be able to spot red objects amidst all the
- green (e.g. reddish poison oak leaves in the green scrub
- oak). He has found that LSD enhances his perception of
- colors, but does not greatly improve his differential
- perception of green. While his hiking companions are
- constantly pointing out red-tailed hawks, red manzanita
- bark, or the poison oak he's currently standing in, he
- still has problems picking them out of a green background.
-
- So when the iodopsin in one or more of the sets of cones
- is abnormal, the signals being sent to the brain are
- the same, with or without psychadelics. How the brain
- on LSD recognizes these signals may be different, but he
- hasn't found that the green perception improves.
-
- But he's continuing the therapy in hopes of improvement...
-
- As far as *visuals* are concerned, he hasn't noticed any
- really special greens that he doesn't see in real life.
-
- But here's a question: does this hypothetical individual
- who is colorblind (total achromat, which is rare) _dream_
- in color? Would he/she know if the dreams were in "color"?
- Would he/she know if the hallucinations were in "color"?
