I'm not color color blind and see a huge difference between LCD and OLED display backlight (the former has one the latter uses its subpixels to make light and therefore doesn't have a backlight) the thing is, I don't care. What baffles me is that if you are attuned to seeing contrast issues... how do you not get annoyed by burn-in (which effects contrast on OLED panels with content that becomes trapped on-screen via image retention)? Well, anyway... Maybe what your wife actually means is that the difference isn't important to her instead of the difference being invisible?
might be a really weird suggestion for a video, but here is one fun thing you can do (rhough it may cost quite some money, no one has done that before, atl on youtube). 1)Buy a UV camera, make fov-angle settings the same as your normal camer, place them really really close to each other. Make a video. And then, replace the blue channel, which what uv camera had filmed. This way green pixels will no longer represent what our eyes yee as blue, but ultraviolet. This should kinda show what humans would see, if our short cones would evolve (or de-volve) for shorter wavelengths. (ik, two cameras may have dfferent settings and stuff and picture wont allign perfectly all the time but in viritasium's video about UV light everything is fine, though they just did a splitscreen). 2)You cna also try this: blue pixels now show UV; Green pixels now show blue (so that, you know, there isnt a weird distance between green and uv). 3) Rry things above with Ultrared. 4) Try changing coloue channles of a video (change green to red, and red with green) and you'll have same colour vision as tripania (or whatever this kind of CVD is called). It's not what they see in their head of course, but youll be able to understand the same colour pairs and stuff, etc... What do you think about it?
One question, what would vision without rods be like? I tried to look that up, and found nohing. But surely, it's possible to have some kind of mutation, or physical problem that would cause only rods to stop working right? What vision would it be? Is this that problematic.
Thanks for the question! It is definitely possible to lose your rods and not your cones. However, rods have no effect on your daytime vision and don't affect your color perception, so during the day, you wouldn't even notice a change. Actually, your peripheral color vision might even improve. However, your night vision would be GONE. Even on a full moon you probably wouldn't see much more than the moon itself. You can google a condition called Nyctalopia for more info.
good job. Btw, now We could say that 3 colour vision is probably the best for humans, since we get all the bonuses of simpler colourvision, and can still see lots of colours.
That's the beauty of evolutionary equilibrium. Hard to say with humans though, considering our habitat has been changing so fast for the last 10000 years and our color vision would not have had time to "catch up" and reach equilibrium again. Maybe we'd be fitter as tetrachromats. Maybe we'd be fitter as dichromats!
Ok, I apologize to my mammalian ancestors. I meant a light slap on the cheak. Why would I keep my color vision? Because its cool. It makes the world so much more interesting. I'm not color deficient in any way but I watch videos often with a color deficiency simulator turned on in order to get a new perspective on colors. As a game/app designer not only knowing how color deficiency works but also *how it feels* is in my opinion essential. My experience with tetrachromacy: (context: I'm a 23yo male human with normal trichromacy, so sadly not a tetrachromatic vision candidate.) After exploring what less cones feel like I wanted to explore what more cones might feel like. I'm currently working on an app (for the moment on my cell phone but later either AR or VR) that implements impossible colors into one's color spectrum. This uses a concept known as binocular rivalry. Each eye receives a different color input (e.g. left: blue, right: green) but the same picture (of e.g. a tree) so that everything seems normal but two colors overlap in an normally impossible way. Although - strictly speaking - I haven't seen any "new" colors with it, however I've seen many more color combinations I thought were impossible in their richness and quantity. After all, a normal Cyan that is a S and M cone mix is (in my experience) a completely different Cyan that you get from combining blue and green with the help of a binocular overlap (e.g. crossing one's eyes). Once I get a VR headset into my hands ("varjo" seems promising) that has good color pass-through, then I'll be able to enlargen the human color spectrum with a good amount of impossible colors without the need to cross one's eyes in order to overlap two tiny pictures on a smart phone. I'm doing this kind of app/AR/VR-driven 'impossible color' research for only a few weeks now but I feel like I've already seen more colors than my whole entire life. The brilliance of a sky that not only shines cobalt blue but also yellow-blue, cobalt-orange-blue, green-purple and red-white - or - a night drive where everything shimmers yellow-purple, turquoise-red, green-blue and yellow-blue is almost indescribable. In this way a normal sunset can get 1 to 6 or more colors. Colorful artwork becomes stale in comparison to the colors I saw. I have glasses that simulate protanomaly and with the help of this app I can easily differentiate between yellow and green. But I can't "see" yellow and green with that, only differentiate it as a mixture of e.g. yellow and blue overlapping (while also retaining normal protanomaly color vision on the other eye, if wanted). This is how I imagine tetrachromatic vision to be like. A multitude of colors I can only attempt to describe if I experience them. And only after rigorous training I'd be able to describe what I saw; with the added issue that no one else would be able to relate (if its innate and not gained by technology).
haha, yea, sorry for picking on you! :p Binocular Fusion is pretty interesting. There are chromagen lenses that are just a red filter you put on one of your eyes, and the binocular disparity is supposed to help dichromats gain another dimension of color vision. Of course, that same solution, or maybe with a slightly different filter, would just as easily (hypothetically) give trichromats another dimension of color vision and turn them into pseudo-tetrachromats. How fluidly humans can effectively use the binocular disparity to see NEW colors is... controversial to say the least. I think my explanation for tetrachromacy would just be "take every color you know... and now there is an A version and B version that you can differentiate of that color. Purple A and Purple B are now two differntiable colors." Pretty much the same as going from a dichromat to a trichromat when y'all gotta explain that you see blurple as two distinct colors. What kind of protan glasses do you have?
@@Chromaphobe It's glasses with cyan (cyanish) lenses that block a good amount of red light. So red becomes almost black (but still red) and orange, yellow, green and turquoise become the same color (a more yellowish than greenish mix) just with a slightly different brightness each. Cyan becomes white and cobalt-blue, purple, magenta and pink become blue. Still just a simulation and not the real thing, but close enough for me.
I'm familiar with the glasses in theory, but I've only found one provider that makes them and they're out of business. Where did you get them? I got some cyan tinted gels, but it doesn't have anywhere near the same effect as CVsimulator (according to my wife).

Sometimes I dream about humanity randomly getting evolved like, in one generation everyone gets tetrochromatic vision, or everyone gets better brains. Just, imagine if all people became x10 as smart. Would be cool. (don't imagine all the conflicts that might occur, just imagine they won't happen)

The whole CVD liking contrast might be why I’m so obsessed with OLEDs. My wife says she doesn’t see a difference.

True, when we craft a habitat to suit our abilities, any deviation is probably less fit.
