If you gave a color blind mortal something like LSD or some other sort of hallucinogenic drug , would they see colors they could n’t before ?
First a little fuze on color blindness from the serious people atColorBlindAwareness.org :
Most colour blind citizenry are able to see thing as clearly as other citizenry but they ineffectual to fully ‘ see ’ red , green or blue Light Within . There are different types of colour blindness and there are extremely rare cases where people are ineffective to see any colour at all .
The power to see colours is entirely due to certain photoreceptors called “ cones ” site in your eyeballs . Normal eyes contain three distinct kinds of cone that work together to perceive colours . However , in multitude with color visual sense deficiency ( CVD ):
… unremarkably there is something incorrect with one of those different cone types . Either they are faulty or leave out … This means you still can see colors but less . Maybe less diverse , less shade , less coloring material and definitely less colorful .
Interestingly , there is a heavy business deal of crossover in how people affect by protanopia ( crimson Christ Within dichromatopsia ) and deuteranopia ( green lighter dichromia ) see the world , as such “ crimson / greenish colour sightlessness ” is often used as a catchall term . As a side note , this is also by far the most unwashed form of CVD .
So what happens when people abide from one of these conditions contain hallucinogenic drugs ? Well , the annoyingly curt answer is that it depends . For example , as we ’ve discussed before , even masses who are totally unreasoning are capable to “ see ” thing in their dream so long as they have n’t been blind since birth . In a similar way , certain blind mass are able to have optical hallucinogenic misstep when they take psychedelic drugs .
We cognize this because , among other subject area , in 1963 , Dr Alex E. Krill et al publish a paper , Effects of a Hallucinogenic Agent in Totally unsighted Subjects , in which they gave a group of 24 “ completely ” blind people LSD in an attempt to actuate them to experience optical hallucinations of some form . The experiment , though small in sample - sizing , did show that , as with unsighted dreaming , “ Such phenomena ( hallucinations ) occurred only in blind subjects who reported prior visual activity … ”
So that ’s unsighted people . How about the great unwashed with CVD ? It seems no one has yet done a scientific study covering this , or at least not published or translated it into English . Without that , what we have to lick with to answer this question is , alas , anecdotal evidence and a bit of conjecture .
We found numerous accounts from reckon CVD individuals during the grade of research this one ; the most reputable of which can be found inThe Erowid Experience vault , dedicate to catalogue the vary responses hoi polloi have to “ psychoactive plants and chemicals . ” In it , they state ,
There are a smattering of case reports of people with color blindness finding that LSD altered their percept of color for the duration of the effect .
If , like we were , you ’re initially a little sceptical of Erowid ’s legitimacy , we should manoeuver out the website currently has over 100,000 different debut and that reports submitted take an norm of about 6 months to be published after they are reviewed for truth and credibleness . Further , Erowid is pretty extensively referenced in scientific papers , admit ones bring out in passing reputable medical diary … So , that ’s something I guess- still not a fan of anecdotical grounds , but here we are .
So what did the reviewed submission on Erowid say ? Here are a duet of the most pertinent for your meter reading pleasure :
I am red green colorblind . I do n’t see in black and white but I can not distinguish two colors of similar shades and I miss almost every number in the colorblindness examination with the coloured dots at the optometrist ’s ( oculus doctor ) .
Since I have done psychedelics , especially LSD and AMT , color have become sharper and brighter and I can more well differentiate like spook in bright and pastel color , but darker colors such as sullen blue sky and purple , have become more unmanageable to distinguish because they seem to morph into each other . I do see all the colors and patterns very vividly when I trigger off and it seems I can more easily see them than can the people I trip with , most of the time I still see stuff after everyone else has come down . I ca n’t tell you if the colors and design are the same as citizenry with normal vision , because I do n’t know what normal vision is . Since I have spark off I have chat the oculist once and buzz off 8 of 15 numbers correctly in the colorblindness test when before I would only get 3 at the most .
And another :
… the arriver of morning heralded the greatest visual experience I could have ever imagined ; For the first time in my life , I saw people of colour .
I am at the utmost end of the colour blindness scale leaf , not quite monochromous , but close enough for me to misinterpret all but the most vivid of colouring . Yet under the influence of LSD , my colour perceptions commence to deepen . At first , I put this down to mere ocular hallucination , but steadily I began to detect , for the first time a difference in appearance between the leave of a tree and its barque . Attempting to canvas this difference was at first difficult , due to the fact that the leaves were consistently change into shuttlecock , faces , cakes , kite , etc … Once I had become customary to the intensely optical nature of the drug , I startle to explore my environment in more profundity .
Until this pointedness , I had always relied upon the shade of an object to determine its colour ; localise it into a ‘ grouping ’ , such as red / green / brown , puritanical / purple / pinko , orangish / yellow / light - dark-green and so on . During my LSD experience , it began to determine between what I can only discover as the ‘ hue ’ of colour . My inability to be any clearer is not due to deficiency of observation , but due to want of reference point . Indeed , during one moment of intense elation , I remember giggling wildly , weeping at nature ’s real beauty and talking directly to the colours saying , ‘ I can see you , but I do n’t know what to call you … ! ’
… I decided to calm down a little and begin a serious study of the effects upon my colour perceptual experience . Therefore , I initiate my admirer into my experiments and we begin testing with whatever was useable . The most outlandish element to these experiments was the need to spend an hour learning all of the colours from scratch . Once I had a optical reference spot , he essay me with various item , such as coloured pencils , leaves and magazine . We even undertake an on-line Ishihara Test for Colour Blindness , once we had retired indoors , but this was not successful due to the fact that the dots continually morphed into one another .
After several hours , my friend , who has unimpaired colour vision , determined that I could indeed see colour …
Kind of makes you wonder , “ How do I know the same colour blue to you is the same color blue to me ? ”
Other anecdotal evidence we came across has many account visual hallucinations , but not in any dissimilar coloring than they normal see . This is why we brought up the good example of some “ all ” blind people being capable to experience dreams and hallucinations ; in those subject the unreasoning people were only able to do so because they had an grain , earlier computer memory of what colours and human body actually looked like . Their brains had a character reference point . Most people stick out from CVD have no such luxury since the experimental condition is often present from birth .
So for many their thinker would be ineffectual to “ manufacture , ” say , green the same mode a somebody who is totally unsighted from birth ca n’t conjure up an figure of speech of a fiendish goat colossus playing the sax or other such common ocular imagery that we of the examine sentiment are so intimate with .
But there are a few anecdotal vitrine where some , like those above , describe seeing color they could n’t before . There are mass out there who become affected with CVD later in life , even sometimes not actually remembering having been capable to see sure colors ; Shaken Baby Syndrome , direct damage through the middle , degenerative eye disease , and side effects from sure medications are just some of the many ways one can have been pay with normal colour perceptual experience and potentially drop off it without ever knowing one had it , depending on when the loss happen . You could even potentially lose it as a minor or even a teen and might not realise this if it happens gradually enough . So it ’s possible in at least some of the anecdotal cases where the individual believes they are seeing some colour for the first metre , it is because of this- similar to blind individuals who could see when they were comport . Their brainpower have a consultation , even if they are n’t conscious of it .
As for being able to identify colour consistently as described in the latter anecdotal tale above , on the airfoil at least , this would seem somewhat unlikely return their eyes would suddenly have to start lick in a style they ’ve never work before . Thoughcertain Robins can see charismatic fields , human do n’t have the power . When you take a hallucinogenic drug , you may * think * you’re able to see magnetized field of operation , but it ’s go to be all in your head and the fields wo n’t be an precise representation of the genuine magnetic battleground around you .
That said , in certain person , it may be that the specific underlying reason of their color cecity is such that the photoreceptors are there , just not working properly and that some hallucinogenics may alleviate the photoreceptors working ( or being more tender ) , whether temporarily or apparently more for good , as in the first story above , accept it ’s true . This does n’t seem too implausible contribute that hallucinogenic drug seem to regard serotonin receptors , which in play affect the passing of legion neurotransmitter . It ’s potential at least , though I ’ll leave it to neurologists to say just how potential ( or not ) this is .
It is love that “ some user of LSD may have a free burning or irreversible constipation in colour discrimination . ” So we do live it can go the other way . And from this , and several other studies , that the specific nerves in question are being affected .
In the end , as no one has yet done a scientific study on colour blindness and hallucinogenic drugs , it ’s hard to come up with a definitive answer for this one . Based on the studies done on blind people taking hallucinogens , it would seem potential that for many color unsighted people who at some point originally in their lives had seen certain colours , they later in life would be able to see these coloring again when hallucinating .
But , as noted , there are some individuals who take they can see colours they had n’t before . During the class of our inquiry , we were even able-bodied to find a documented illustration of a guy with red / green CVD being able to see properly again after ( accidentally ) smash his face into the floor . This plain wo n’t work for the immense bulk of others with CVD ; but it may be that some person who have all the necessary hardware , so to speak , but not working by rights , are able-bodied to temporarily “ switch ” the hardware on or make the sense organ more sensible with psychodelic drug . But we ’ll hold back until someone does a study on this to give a more classic response . If the first story above really is true , it would seem that someone really should be researching this as a possible therapeutic ( or starting point for a curative ) for color sightlessness in some someone .

Bonus Facts :
Contrary to popular belief , dogs and CT can see colour .
Before her instructor first come to her , Helen Keller , in her autobiography , stated “ My dreams have funnily alter during the retiring twelve years . Before and after my teacher first came to me , they were barren of audio , of thought or emotion of any kind , except fear , and only came in the grade of champion . I would often woolgather that I run into a still , dark room , and that , while I stood there , I felt something fall heavily without any noise , causing the story to shake up and down violently ; and each prison term I waken up with a jump . As I learned more and more about the object around me , this strange ambition ceased to haunt me ; but I was in a high body politic of excitement and received impressions very easily . It is not unusual then that I dreamed at the clip of a wolf , which seemed to rush towards me and put his cruel teeth deep into my body ! I could not speak ( the fact was , I could only spell with my fingers ) , and I try out to squall ; but no strait escaped from my lips . It is very likely that I had heard the fib of Red Riding Hood , and was deeply impressed by it . This aspiration , however , authorize out in clock time , and I commence to woolgather of object outside myself . ” If you ’re wondering how she “ heard ” the fib of Red Riding Hood , it ’s because , wayward to popular feeling , Helen Keller was not bear blind or indifferent .
