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, but there are also dichromats who see fewer colors -- as well as tetrachromats who can see a hundred million colors. But even if you can see those extra millions of colors, it's a bit difficult to describe them to others in words. [url]
- Movie posters from 1914 to 2012 are mostly blue and orange. The distribution of colors isn't too even, and the spread of the use of blue appears to be growing over time. [url]
- The color of food can really affect how it tastes. Red-colored drinks seem to taste sweeter for some people, and people are pretty bad at tasting flavors when the color of a drink doesn't match its flavor. [url]
- Adults and infants may perceive colors very differently -- with babies seeing colors directly, but adults seeing colors based on language interpretations. Interestingly, some Russian speakers may be able to see more shades of blue than English speakers. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

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.

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.

Re:
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".

Re: Re:
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.

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

Re: Re: Poster colors
Film studios don't do posters any more, but they used to charge more for red. Hence the palette was limited. Coca-cola didn't do movie posters.
