@Alekz: Are the family members who see the lighter bands as white male or female?
As my small investigation showed, it does not matter. My daughter had a theory (that was working for the first 10 people ), that intuitive persons should see b&b and sensing w&g, but it failed miserably as soon as we were close to 20. Same personality types see different colours. Then I had another idea - within one couple (does not matter if they are married, live together or just boyfriend/girlfriend) both visions are present. I have results for only 7 couples, but with 100% correlation so far
Our hearing is also very distorted. Remember that article about how our ear works? A series of mechanical filters and compressors. And only then we have the brain. The chain is much longer than for the vision, so the differences should be more pronounced.
The above link is from another forum . I posed the same question. Although here the replies were very elighting this forum was also very good and worth while for all to read.
How we hear was not the the answers I received there although I some wags the answers were about the topic but more focussed on what it should be for us.
Interesting. I finally read the Wired article and I am not as familiar with the contextual nature of color perception as I am with more clinical methods of color vision measurement. In a measurement sense, color vision is not a black and white sort of thing (sorry, couldn’t help my droll self). There is a continuum of differences in color vision. Most of us think in terms of the tests that we had in grade school to filter out the red/green and blue/yellow “colorblind” kids. In fact, wide differences exist between the “colorblind” individuals. Some are rather profoundly unable to distinguish hues, others more mildly. If you use more detailed tests to categorize “normal” people you find that color vision differences are quite subtle and widespread. One test, the Munsell 100 hue test, has you physically arrange 100 bottle caps with colored tops in the ROYGBIV order. The colors of two adjacent bottle caps are very close and performing this test is maddening. Some are able to perfectly order the caps, others not so much. There is no time constraint and the subject is able to peruse the line up in it’s finished order and make changes freely. The test is performed in “standard northern daylight” for consistency. Most errors consist of transpositions, where the order of two adjacent caps are mixed up. Making the colorblind kid do this test would be like forcing your grandmother to beat a puppy.
“Optic Yellow” is the color of many yellow tennis balls but I’m not certain that it is a trade mark. That yellow-green color of some emergency vehicles is the color that our eyes are most sensitive to. Colors, differing frequencies of light, don’t all focus on the retina. Blue’s focal point is in front and red is behind (remember refraction?). The brain usually does a good job of “not noticing” this but it is measurable. This is one reason that the red/blue 3D effect is not as pleasant to look at as the crossed polaroids technique used in 3D movies today.
At least my Optometry training did not totally go to waste!
They do not own them, but have a protected commercial interest via trademark. They possess an exclusive right to use the trademark or servicemark in commerce and to stop infringement by competitors.
But, as you noted, it still seems odd in a way that a company can have a proprietary interest in a color.

How fascinating. It is amazing our little brains are able to get an image at all out of the information it receives.
Good one. This is great. The Bar/Far thing is an extension of the visual capture phenomenon. I learned that vision always dominates the other senses but the two tones and the flashing dot runs against this. In the side by side clip of the fellow mouthing “Bar and Far” if you look back and forth between each “Bar” it will sound different each time. Bar,far,bar,far… cool.
