the OP is talking about colour. not conformating of teaching your self someting is something else

means
someone reading this physically sees it as the same range as blood.. traffic stop lights

but some people see it as grey(colour blind)
this is because their eye cant tell the light frequency of the red spectrum so just throws it into the monochrome spectrum

however the colours are not randomly picked as you grow to associate tomato/blood/traffic stops with the english word red.

its actually your brain knowing the frequency wavelengths of light

its not that a red wavelength refracts in the eye to change colour (to a totally different wave length).
a strawberry emit the same frequency to everyone (unless colourblind) and everyone brain knows its the same frequency they all get

as for assigning a colour to that frequency
this is not some pot luck brain trick of randomly taging a shade to a frequency.

because the frequency has minor alterations

because if you picked randomly that
400nm was what we deem yellow
425nm was what we deem blue

then because theres no increment of green inbetween. we would see a weird sudden colour swap of yellow-blue rather than a nice progression of violet to indego
imagine instead of a steady smooth transition it was instead
||||||

looks ugly.. no pattern. no reference of it being linked to any close nearby shade

so knowing when you are seeing strawberry red.. you and everyone else is seeing its near the orange and pink family but no where near the blue family of frequency

..
next is the false theory that people have different assigned spectrum start-end 'colors'
EG
VBGYOR
BGYORV
GYORVB
YORVBG
ORVBGY
RVBGYO
but this is not the case.
each shade goes from darkest at the edges to clear/brightest at the centre
so white/yellow will always be the centre
yep whatis the sun.. and pure blinding light.. is the center colour. and yes its white/yellow

which can then only leave 2 options of formating the brains colour spectrum
VBGYOR
ROYGBV

black dark forms at both the ends of the spectrum
but knowing a dark purple/blue sky is at one side and dark red at the other.

your brain knows that purple is at the lower bands and reds at the higher bands of the nm wavelegth
so the order is
VBGYOR

it definetly wont start with yellow and end with blue and red beside each other at the other end

people can actually say orange in 1 direction turns to yellow and in other direction turns to red. when presented with known wavelengths.
and they all see their vision no longer able to see whats beyond the red spectrum(infrared). so they know red is the final shade. then going backward. they know that violet is the first colour they see when coming from ultraviolet(375) to the visible violet spectrum of 400nm

This is awesome
