Colors

Every wonder if my blue is your red?

We may both look at a car we both agree to be blue. I've grown up knowing the color I see on the car as blue. But you see the car as what I call red. But you grew up recognizing my red as blue. So we both call it blue, even though I would call it red if I looked through your eyes.

Get it?:confused:

Yes, I've wondered that before too.

And, even though we've done eye-transplants, we can never really know because it would be how the brain recognizes it, eh?

Yes I've wondered the same thing many times myself. I have a friend who is partially color blind and cannot distinguish blues from greys, but naturally most people can distinguish between different colors. But it is a large assumption to think that all people see them the same. For example, I've always thought that "yellow" lights (at intersections) appear more close to orange, while I know many who insist they are yellow. I am assuming this is a bit of a grey area between people's different visions. You can find that a lot of in-between colors (like sahdes of turquoise and aqua blue) may be described differently by different people, largely because of differences in their respective visions. Interesting argument!

Generally, women see colors better than men, so if they say your clothes don't match, they are right! :D

another interesting thing about color is that people who work with it all the time (designers, painters, people like me who do digital retouching) can generally distinguish between much more subtle variations than the average person. I read one study that said color professionals can see up to ten times more tonal variation than the average human. And I've noticed this many times sitting with clients making color changes, where I will make very small moves to color that they don't even see reliably (yet I can see just fine). Seeing color is just like anything else evidently, the more you focus on it the better your sight skills become in seeing it.

well actually not to get scientific and ruin the fun but its all based on wavelengths.. and when you go to the dr to get your ice checked that is pretty much waht he is checking is how well your eyes can interprit those wavelengths.. a human eye can only see a small scall of the spectrum called the "visible spectrum" above it you have ultra violet and below you have things like radio waves.. it also has to do with pigment which change the regular suns light into a different wavelength, as it is reflected off this small particle, into a diff wavelenth.. :) well that is what my damn biology teacher told me anyways.. but hell the guy is weird :)

heh

That doesn't answer the question or theory though.

well actually it does... see because they have tested that peoples eyes can pick up a certain wavelength... and they know for sure that pigment changes lights wavelenth (which appears white cause all colors are mixed) and reflects only a certain wavelength which your eye picks up and decifers, but they have done many tests on this.. i saw it in one of the recent scientific americans.. but that is just me quoting them im not saying im a scientist :)

How do designers and painters get there 10X better tonal distingiushing ability?

They adapt and EVOLVE that way I guess. Unless god makes them see better... :D

oh god here we go again :).. i think we should stay clear of your last two posts haha... or else we are going to have one long and tedious thread ;)... i say we wait to see someone elses opinon before any of us reply haha..

w00t!

Yeah, lets stay out of evolution/creation here.

And I, a creationist, agree that artist's eyes have adapted, through practice and training, to see the different colors, if God made them that way, they would have always been like that (contradicting normal, say, accountants that switch to being artists halfway down the road). Same as those people that have slowly trained their nose to distinguish like 5000+ smells.

It's all in how you are brought up I guess. It's probably because those people just spent their whole/most of lives doing something (generally) like looking at colors.

i agree!! hehe we agree for once lol.... well i wasn't really brought up as a christian.. i mean i went to church occassionally when i was little but after i was about 9 or 10 i stopped going... and really havent been since.. i guess i just chose it? :confused:

I think he meant being brought up looking at paintings vs. being brought up playing with dinky cars (me :D), for example.

Everyone played with little cars!! I used to crush them in vices and shit. :D I'd also throw them down the stairs to see who could jump the farthest., putting scratches on the little cars and the floor!:eek:

w00t!

I here there worth something now.

"I here there worth something now"
You mean: "I hear they're worth something now."
:D

By using their sense of sight so much more often to try and distinguish subtle color variation. And no this isn't adaption or evolution MBTN, it's the same prinicple as heightening any part of the body through continued use (weight training, cardiovascular training; the brain gets better at performing tasks once they've been done a thousand times over too). Remember our sight is based not only on our eyes, but more accurately our brain's interpretation of those electrical signals. Better interpretation = better sight.

:D So how do you explain Slime Green Pontiac Azteks?

Pontiac Azteks should not be brought up at any time from now one. Anyone who does shall be hanged. :D

lol MBTN...those slime green ones are the worst of the worst.

I kept all my dinkys in perfect condition...I still have most of them (500+) everything from Ferrari F50's to Dodge Omnis. I wish the dinky car companies still made everyday cars like the Omni, and not just the exotics (which are nice as well).

I said NOT to bring it up anymore! :D

Y'know about those Azteks... no no, I won't say it. They say wine tasters also have improved taste than the rest of the population. That's one thing I could like without. After a day of tasting really great stuff, you have to either go home and cook for hours to get something to taste half decent, or go spend a lot of cash. I'll stick with my taste abilities that still say that mac and cheese is good food.

Sorry to dig up an old topic, but this was something interesting that I read about a while back.

Summary: Most people are trichromats, with retinas having three kinds of color sensors, called cone photopigments -- those for red, green, and blue. The 8 percent of men who are color-blind typically have the cone photopigment for blue but are either missing one of the other colors, or the men have them, in effect, for two very slightly different reds or greens. A tetrachromat would have a fourth cone photopigment, for a color between red and green.

For years now, scientists have known that some fraction of women have four different cone photopigments in their retinas. The question still remains, however, whether any of these females have the neural circuitry that enables them to enjoy a different -- surely richer -- visual experience than the common run of humanity sees. "If we could identify these tetrachromats, it would speak directly to the ability of the brain to organize itself to take advantage of novel stimuli," says Dr. Neitz. "It would make us a lot more optimistic about doing a gene therapy for color blindness."


If this intrigues you, I suggest following the link.

yeah, i read a huge thing about tetrachromats on slashdot. it was really cool. what if they could find those people and give (somehow) us trichromats a 4th receptor.... sooo sweet. ferarri's would be sexier still.

What about the way colors invoke emotions? That's clinically proven, and advertising uses it all the time. If blue makes me feel sad, let's say, and your "blue" which is my red makes you fell sad... I forgot my point... :bloated: anyone get enough of that to figure out what I was going to say? :bloated: Dur, dur, dur to me today!

*Using a megaphone*

Back away from the skittles man!!! No one needs to get hurt!!:D :D

But what if you were told by your parents from an early age that blue was red, green was yellow etc. It would make school interesting I supose :D

i had to re-read that a couple times but now i get it!! :D

yeah that's weird, i half feel like it's true and then half feel like ah we all see the same thing
