DailyDirt: Blue-Green Or Green-Blue Crayons?

from the urls-we-dig-up dept

Human perception can be pretty strange sometimes. People with synesthesia experience some mixing of their senses, so that they can hear colors or taste colors. But the English language even contains some interesting phrases to describe various feelings, such as “green with envy”. Here are just a few more interesting examples of sensory perception.

“The vast majority of people are trichromats who can perceive about a million shades of color, as well as tetrachromats who can see a hundred million colors.”

Note tetrachromats are rare and not just Women, despite the fact that they have always claimed to see shades of colour that most men struggle to pretend to agree to seeing a difference in.
(this could just be me)

I may be exposing my ignorance here, but I’ve always wondered; How do we know that everyone (well, the majority anyway) sees the same colors? I mean, a person’s only outside reference for what a color is supposed to look like is what they’ve been told that it is. How do we really know that everyone sees the colors of the spectrum in the same order?

You’ve been taught that the sky is blue, so when someone shows you a blue crayon or blue paint and asks what color it is, you say “blue” because it’s the same color as the sky. But what if the color you see when you look up is the color I see as yellow? Maybe someone else sees green. But since they’ve always seen that, it’s perfectly normal to them.

Take a prism and shift it a little and the color of the light passing through it changes, so what if there are minute differences in the ‘prisms’ of people’s eyes/brains that cause them to see the same range of colors, but in a different order.

If this were true, there would be virtually no way to verify it, since there’s no way you can ever see through someone else’s eyes.

What the brain “sees” as a color may differ but the order will be the same. We see a particular color due to its frequency, if that frequency changes so does the color.

“the color I see as yellow? Maybe someone else sees green. But since they’ve always seen that, it’s perfectly normal to them.”

Exactly

Which way is up and which is down?
The image projected upon your retina is inverted due to the convex lenses in your eye, your brain compensates for this and you end up seeing things “correctly”.

OK, maybe I worded that a little awkwardly. What I meant was that when one person looks at the spectrum, they might see;

ROYGBIV

And when another looks at it, they might see the colors;

GBIVROY

Seeing green where the first person sees red and so on. But since they’ve been taught that “red” is the first color, whatever color they see in the first position becomes “red” to them.

CIE Standard Observer

The CIE XYZ colour space was defined in 1931 in terms of the colour sensitivity of the eyes of a ?standard observer?. This was an average of measurements of a bunch of individuals?I can?t find an online reference for how many, but it might have been a few thousand.

So it?s long been known that colour perception varies between people.
