so when I was a kid I used to think that
people with blue eyes saw the world
through a blue tent and people with
three and I saw the world through a
green tent now of course that’s not
adult I understand that that’s super
silly and that we all practically see
the world through the same lens except
for perhaps maybe our friends with
colorblindness this image is a graphical
representation of the colorblind
awareness and department for education
and government equalities annotation
that specifically annotates different
parts of the population that there were
different forms of colorblindness what
I’d like for you to do is fold focus or
fix that your attention towards the top
of the image because throughout my talk
I’m gonna be kind of pushing back
against this idea of normal color vision
do any of you by any chance remember
so for those of you who may not know
this dress broke the internet in early
2015 and if I could I just like to get a
show of hands how many of you see the
and how many of you see the dress has
black and blue cool so today my job here
is to give in to you that because that
you think that you’re seeing might not
actually be there but that we all may be
hearing the same colors but to do that
we’re going to again need to have the
talk the synesthesia talk that is so by
now you may be asking yourself what
exactly is synesthesia
well it’s described as sensory
impressions that relate to one sense by
the stimulation of another simply put a
synesthetes noble senses like taste
sight and smell are all a bit
interconnected causing for a whole
cacophony of sensory expressions now I
found this very interesting so I decided
to dedicate quite some time into
researching the condition and created on
works that were directly inspired by it
my research led me to a very specific
subset of synesthesia but probably one
of the most well known called chroma
Stasia
or sound to color synesthesia I wanted
to see if there is a way to simulate the
experience of proneness chroma stiva for
individuals who didn’t have the
condition and as it turns out it kind of
can’t be done the reason for this is
because chroma stevia much like
synesthesia are extremely individual
experiences kind of like that dress so
for the next couple of minutes I’m going
to need your attention and your health
while I do a little bit of explaining if
you would fixate your eyes and your
attention on one specific part of this
image now where it is on this image can
be anywhere it’s totally up to you we’ll
just make sure that it’s only one part
and this next part is just to boy your
eyes and not you but look at that and
make sure you hearing me while you stare
at that image your eyes and the rods and
cones of your eyes are going through
something called neuro adaptation or a
loss and sensory responsiveness this
means that because your eyes aren’t
getting constant stimulus certain light
receptors in your eyes kind of turned
off and thus causing you to see
something that actually isn’t there now
this phenomenon that you just
experienced is called complementary
actor image and by now the after image
after image is probably dissipated but
as we all saw color was a little bit
deceitful
now these are all degrees of the sea
based on what we can see but what do we
were actually hearing colors that were
in present this is a direct frequency
the wavelength child and we’re going to
use this as the basis for hearing color
because again synesthesia and chroma
stage are individual experiences let’s
do our best to use the numbers our eyes
have three main light receptors we have
red which clocks in at about 6:20 to 740
nanometers of light or the harmonic
frequency equivalent of a G or a g-shot
for simplicity’s safe in this example
let’s use the G shot continuing on we
have green which clocks in at around 500
to 560 nanometers of light or the
harmonic frequency equivalent of the C
and we have blue which clocks in at
around four hundred to four hundred and
eighty nanometers of light or the
harmonic equivalent of a t-shirt all of
this resulting in a G sharp major triad
which three notes that are stacked on
top of each other so now that we have
some kind of basis for a sound to color
relationship it’s time you’re visiting
that complimentary after image test and
see what happens this is a view of
Columbia University signature low steps
– a few color defects what I’d like for
you to do is fixate and focus your
attention on the very center of the
image where that white dot is and what
I’m going to do is play the colors that
your eyes want to see and only look away
from the center when the sound stops
okay
now if you noticed this black-and-white
photo was black and white to begin with
but your eyes saw what they wanted to
hear either way so the next time that
you find yourself arguing with your
neighbor about the colors of a dress try
hearing the cause of the dress instead
thank you
