However, super-saturating your eyes with a color and then removing the stimulus effectively allows you to also "subtract" out some light and therefore reach parts of the perceivable-color-spectrum otherwise unobtainable.
I thought it was a clever application but my students didn't seem too impressed!
Thanks for sharing, what a neat thing!
So you can have it render an object which shows different colors to different eyes, while rendering the rest of the scene normally?
What software supports this?
Few years ago they switched to single pass stereo rendering to avoid rendering whole scene twice. In theory this legacy option to use two cameras is still there, but quick googling says that it has some issues on modern Oculus SDK's and new Unity render pipelines but workarounds are possible.
But maybe I'll get back to work on my hack. Some suggestions are here:
I have zero experience with WebVR, but solution you linked seems sensible.
Do you have any idea how to do this? I was trying to hack Three.js to enable binocular presentation (I have only Gear VR headset for my Samsung smartphone), but I wasn't able to do it. And as far as I'm concerned it's the only library providing WebWR functionality.
I'd avoid PSVR, it is obsolete in 2020.
Given their total lack of ethics, I don't think Facebook deserves our $$$. But it's true that the Oculus price is attractive (as with everything where we pay with our privacy)
The biggest thing seems to be the long lead times between ordering and arrival.
I have Oculus CV1 and might upgrade to the Reverb this holiday season for the resolution.

I was rather disappointed.
That's really scary! It's like looking at the sun.

 pedantic alert: yes "every color" is ultimately a mental construct of the brain but hopefully you know what I mean
I don't mean discerning ever finer gradations in existing colors, but entirely new color qualia.
What would it be like? Would our brains be able to integrate this new phenomenal experience?
And most importantly, if color is a property of brains rather than something in the external world, does that imply the number of "possible colors" is infinite? I.e. seeing as biological brains "choose" how to internally represent a particular wavelength of EM radiation, is the seemingly Platonic realm from which these colors are plucked from inexhaustible?
We currently have aesthetic preferences over existing colors. I would want to know whether these possible colors can be enumerated, searched through, and have a utility function placed over them so that each human can find what is to them "the best possible color."
No need for neurosciences, just some fancy spectral filters like those on IMAX 3D glasses. With some practice using these glasses you can experience a six-dimensional color space. When you remove your glasses, this six-dimensional space collapses into the common three-dimensional color space. But with the glasses, you can distinguish many different colors that look exactly the same to regular humans. That white wall? It looks a perfectly uniform white to most people, but you can see clearly that two very different kinds of white have been used here and there.
A similar effect can be obtained indoors by lighting objects with monochromatic lights, but it is not as dramatic as with glasses.
Warning epileptic risk, experiment at your own risk.
You have some led or screen smoothly changing periodically.
Train your brain to discriminate between the two following sequences.
Going from red to green to blue to red. (Species A)
Going from red to blue to green to red. (Species B)
You have to pick the right frequency (i.e. ~10-20hz) fast enough so that your brain sees it as a single unit without thinking about it, but slow enough that is still able to pick some differences.
You can gamify it for example on a screen you can watch color-changing moving balls. And you have to pick one subspecies only.
You can then extend this little game to train your brain to "see" various color rotations (aka rotating a color sphere). It's kind of like learning music. Construct some structure programmatically, then gaze at it until your brain intuitively grasp the underlying structure.
You can also play with the difference of temporal phase if you have some vr-headset you can have a 6D color space input, which you can use to train your brain to visualize 4d rotations, and rotations in higher dimensions spaces which will probably be useful for visualizing QCD intuitively.
If you have the time to train your brain for it you can construct a rotating color based language like you would with music. If you sync-it up to music it can help the learning process by doing some kind of joint training between audio and visual space.
>We also observed one case in which we believe cross activation enables a colorblind synesthete to see numbers tinged with hues he otherwise cannot perceive; charmingly, he refers to these as "Martian colors."
In fact, if the mind color space were actually infinite, it would be essentially impossible that any two organisms would share color perceptions, while in reality we share even the impossible colors.
You may have to watch the video multiple times though, because the information comes out of a firehouse.

I find my mind extremely receptive to these sorts of things when I'm very tired on the edge of sleep.
A good sativa actually opens up quite a bit of pattern recognition and other subtle visual perceptions. One example I can think of is a cardboard box that actually has the manufacturer's logo lightly embossed. You can't really see it at least I never did. But one evening after a good meal and the sativa, I looked at that box and could totally see the subtle difference in the circle for the carport. Interesting lie, I have remained able to see it. Like a little doorway opened.
>looked at that box and could totally see the subtle difference in the surface of the cardboard. Interestingly, I have remained able to see it.
I didn't really perceive it as a "new" colour though.
