Just waiting for him to have his Michael Richards moment, not saying it'll definitely happen but I'd be utterly unsurprised if or when it does.

Saw this on a Cracked article about "strangely satisfying videos".  It really is hypnotic.

Awww takes me back to CDT class in school; every year the teacher would do a lath demonstration and make a bunch of chess pieces, I think the rook I got then is still knocking about in my mother's house. :)

I've got a little Sherline lathe and the parts to convert it to a mill at work, it is fun to take a chunk of metal or plastic and turn it into something needed for a project.  It's the one part of my job I wish was needed more often.

As I posted in the science thread, this technology could finally answer the question of whether my red is the same as your red.

I've always been surprised at how weirded out people are by this phenomenon. I remember people looking at me odd when I would talk about this  in primary school. It didn't get any better till I was taking Psychology A Level then people seemed to understand what I was talking about.

But that's also a slightly different, though related phenomenon.

Of those men in the study they may all have been seeing blue-green but that doesn't mean the colour each was seeing would be what the others would call blue-green except that the shade they were perceiving is called blue-green by consensus, but we don;t know they are actually perceiving the same hue.

So

Guy one sees

While Guy two sees

But to both men that is "blue-green" so they can agree that they are both seeing "blue-green".

No, not this particular difference in perception.

Because they aren't perceiving a colour differently in the sense of identifying it, they're (theoretically) perceiving an agreed upon colour designation differently while still "seeing" the "same" "colour".

No, they can't account for it, that's the point and, in fact, they don't need to.

We don't know what another person perceives as the colour each of us calls Red or Yellow, only that when we all look at something that is red or yellow we agree that it is red, or yellow.  That doesn't mean however that we know everyone is actually seeing the same colour in the sense of how that colour appears to the individual.

That's what the video is about; not observable differences in colour perception but in the fundamental perception itself. :)

Look if I see the colour blue as the colour you would think of as red, that doesn't actually effect whether we can agree that the sky, on a calm and warm day is blue (as an example); we both look up and see the colour we've learned to call "blue". Likewise the difference in fundamental colour perception doesn't effect how we'd do in tests on colour perception like the one you cited, all of those men are indeed seeing green-blue, that isn't effected by whether "green-blue" is seen as the same colour to them as to other people because green-blue is simply the name given to the shade that is between whatever that happen to perceive when looking at the colours they've learned to identify as "green" and "blue".

Now the existence of things like colour blindness make us think that this theory might have some veracity, and I've mentioned before about how I think I perceive colour in such a way that the orange and teal keyed images are more pleasing, but that's only tangentially related to this possible phenomenon. :)

While there might be differences between your blue and my blue, common human experience normalizes our reactions to color, for the most part.  The sun is yellow and orange and hot, trees are cool and green, white is snow and cold.  I would be interested to see a study on people who do not have those common associations and whether they perceive color differently.

The video also seems to claim that color is completely unmeasurable, which isn't true.  For example, I own a color meter, which measures color of light on the kelvin scale and also if there's a green / magenta shift.  The colors of the rainbow are all measurable, as they relate to different frequencies of light, but there are colors that we see that do not correlate to a specific wavelength, like purple, and are instead the combination of wavelengths and the absence of others. 

But they have now found tetrachromats; people who have four cone cells in their eyes instead of three, who can see millions more colors than we can.  The light spectrum is broken down even further into many more shades.  But according to the one confirmed tetrachromat, she was unable to communicate her experience, as the video pointed out.  We do not have the ability to describe color to those who can't see color.

It's even worse for the sense of smell.  I have anosmia, which means I am unable to smell.  I lost the ability around the age of six or seven.  And I find it interesting when people talk about an objects odor, because it's almost always in reference to another smell, and I never walk away with an idea of what the object smells like.  We don't have many adjectives that only relate to smell.  Even when describing a very specific smell, like wine, the adjectives used are all in reference to how other things smell.  You can call something "stinky" but that's a little subjective.  Ask a person to describe it further and all they are able to do is compare it to something else, like shit or burning hair or sulfur.

Yes, that's what I, and the video was saying.

No, it's not saying that.


Apparently this really is very difficult for people to get their heads around, and I still don't understand why.  :-\
