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 withe the english word red.

its actually your brain knowing the frequency wavelengths of light

its not that a red wavelenth refracts in the eye to change colour.
a strawberry emit the same frequency to everyone and unless colourblind everyone brain knows its the ame 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
emagine 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
