Is there a way to, with current technology, implement a continuously variable RGB? My eyes are good for nothing and with the prescription lenses that are available to me, traditional RGB just appears as a mess of red, green, and blue. I want truly variable color, all the way from infrared to ultraviolet.
>implement a continuously variable RGB?
not really. As you say, current LEDs use a mix of modulated red, green, and blue in order to mix up anything in the spectrum, but they don't do it perfectly.
You could use a blackbody source and a diffraction grating, but it would be terribly inefficient and pointless
>Is there a way to, with current technology, implement a continuously variable RGB
if you were even 5% capable of doing anything like this, you wouldn't need to ask here, of all places, if it were possible.
prism + black body
(i.e. a cd and a filament lamp)
Braided fiber optic
>Doubt
You have a profitable future in graphic design otherwise
What the point if your eyes will see it RGB all the same. You have only three color sensor in the eyes, unless you're another species of mammal or bird.
No I mean my lenses do something weird when I look at an RGB light, the colo gets split into the distinct colors. For example and RGB light set to purple, I'll see a strip of red and blue instead of purple.
There are ways to design a system of lenses (instead of a single glasses lens) that would handle color aberration. But you'd need a very specialized person.

Talk to your optometrist. This is a common effect, most people just don't care.
I once made the mistake of inquiring about how to get sapphire lenses on the optometry subreddit and got utterly crucified because "sapphire too brittle and too dangerous for eyeglasses", like frick I don't care, I just want lenses with a high refractive index but minimal chromatic aberration and that doesn't get scratched by paper towel, sapphire is the most ideal material for what I want, but goddamn I'm a fricking idiot for even suggesting it because it might be dangerous in the event of a car crash.
How odd. They.were.made out of literally glass for centuries and it was fine. Slap a film on it if you're worried about it exploding, frick. That sounds nice, glasses that don't get scratched by a paper towel.
I'm glad I'm not the only one who actually wants decent lenses.
As far as things go, plastic/resin lenses are a recent innovation but yet you're a fricking weirdo if you dare want real glass. You otherwise demand sapphire lenses on your newest iPhone but having the same for your actual eyes? GTFO apparently
I guess it fits with the nature of ophthalmology being an outright scam. Most people are OK with shitty lenses because they really don't need much correction in the first place and most ophthalmologists are for those people who need little correction, the same type of people who would honestly be fine without glasses.
If you actually have vision problems that affect your ability to function, then 95% of ophthalmologists flat-out cannot help you. It's sickening tbh.
>I'll see a strip of red and blue instead of purple.
chromatic aberration, yes shitty lenses will do that.
That's what you get for wearing Dollar General glasses.
Ah. I understood your problem now.
Sorry, I don't think you can do anything but blur the pixelled image with some filter

Some human women are potentially tetrachromats, but they probably wouldn't realize it.
Those girls that can tell magenta from fuchsia (just kidding)
Hey cool i never heard of that i think i am
I can see infared under certain conditions
Must be fun seeing people beneath their clothes.
>I can see infared under certain conditions
no you can't
Not him but I can see the purple from infrared LEDs if I try real hard and it's dark, it might just be the LEDs making a little bit of visible light though
depends on the wavelength
something like 850nm you may be able to if it's bright and you're in a fully dark area (although idk if it should really appear purple instead of a deep red, cameras often show it as purple though) 940nm probably not
the point you stop seeing red is obviously a smooth change, so while 650nm is very easy to see (and obviously red), 700nm is harder, 750nm is even harder than that etc. Same goes for the other direction, 450nm is a very obvious blue, 405nm is a much harder to see violet, and 365nm good luck seeing anything (fluorescence also easily hides the true color of the violets)
also makes these edge colors a bit more dangerous, since it may not look very bright (since your eyes barely react) but being able to see it at all means the light is extremely bright
Saw 12x 1310nm laser once that was exciting
What the ever loving frick are you asking about?
I hope this is the right place to ask this instead of starting a new thread.
How do I know if a rgb led stripe store the last used configuration? The ones I had always starts at the same flashing colors. I wanted one that knows the last used color instead of always having to change it in the remote when I turn it on.
