When we look at a rainbow, we see a full spectrum of light. Every colour we could imagine. Except one - magenta.
Where is it? Well, officially magenta doesn't exist. There is no wavelength of light for magenta, meaning the human brain literally makes it up, but how?

Just because magenta is social construct of our minds, does not mean that it doesn't exist. In fact, the whole construct of mind is the very prove of its existence.Месяц назад

How can you speak of "magenta fruits and flowers," i.e., objects with a distinct property read as magenta, not any other color, and say magenta doesn't exist? It's not _one frequency_ of light, sure, but that's true of almost everything we see. At a minimum, this video needs to define some terms.Месяц назад

It is seen as Magenta probably because it emits/reflects extreme red and blue colours simultaneously, that is it has both those pigments in nearly equal amounts .Месяц назад

Well I am going to cause a stir. White light does not exist either, it is a combination of Blue, Green and Red light in equal proportions. The same for yellow (red+green, yeah difficult to believe) and cyan (blue+ green easier to imagine). Remember we are dealing here with LIGHT not pigments. Combine bue + green + red paint and you will not get white but rather a dirty brown.Месяц назад

Actually yellow is a light spectrum in between red and green and also what your brain perceives when you mix red and green light. You can actually see "red-green" which is not yellow by burning your eyes by looking at something that is bright and green for a while, it looks like a very bright version of the color of peanut butter.Месяц назад
There’s trillions of colors in the invisible spectrum… including magenta. It’s called the ultra-violet spectrum.3 дня назад

Given how much you spent on the graphics, I'm surprised you didn't spend more time on your research. There are other extra spectral colours. The most obvious being purple.Месяц назад
@Yogi Barista best response I've read this far. Thanks9 дней назад

The spectrum ranges R-O-Y-G-B-I-V and anywhere in that continuous range is a corresponding wavelength for a colour we see. But our brain is also able to assemble composite colours, such as Magenta, Brown, White, etc that are not part of the spectrum. So the point is that if composite colours are not part of the light spectrum we evolved with, how and why did we develop the ability to "see" these composite colours and determine what they should look like ?Месяц назад

Magenta is purple, but you are right about spectrally discontinous colours; spectral filters, made from very thin deposits of glass which cancel very narrow bands of the spectrum through destructive interference, is the basis for eye glasses marketed at people with various forms of "colour blindness" (anomalous trichromatism).Месяц назад
Magenta is fake because it’s not in the spectrum Me: Pink white and periwinkle aren’t in the spectrum either does that mean their fake too😅😜🤣😅😅😅Месяц назад
magenta : A source that emits or reflects BOTH 700nm red lght and 450 nm blue is perceived by humans as as magenta. As far a human eyesight is concerned, some people see IR light which has a greater wave length than Red light... most others can NOT perceive IR light . I agree with ArtistBervucci below. How can the word "exist" apply to the reaction of one's sense of sight, or hearing or touch? Does human reaction to the color magenta from a rotting, dead body and the red of a beautiful flower DIFFER ?Месяц назад

Magenta makes sense that it's the odd one because it's the gayest color there is.Месяц назад

Prisms only creates a linear spectrum of separated light and if you mixed one end with the other then you get magenta, with the colours of red and blue. The brain doesn’t just make up the colour, nature produces it, like with any other colour and to think it does is just very silly and you shouldn’t teach such things as fact. If you worked in a photography laboratory in the past you would have quickly been sacked, if you believed in such things, as you wouldn't know how to use the kit. In old school photography and photographic printing plus in TV, we used two different triads of the true light spectrum and not one just separated by triangular shaped glass. In the old TV sets, we had red, green and blue guns and which when mixed correctly, could make any other colour. With yellow being made from the red and green guns and which was used due to being pure light and so, there was no matter pigment distorting the pure yellow colour and so also proving, there is no such thing as a primary colour. In photography we had to use cyan, magenta and yellow and which when mixed correctly could also make any colour. This triad was used due to the medium having to use pigments and which distorts the colour and so when mixing red and green, will give you brown and which is nothing more than a dirt yellow. To make red, we use magenta and yellow. To make blue we use magenta and cyan and to make green we use yellow and cyan. With the different two triads when viewed together as a spectrum, giving one of the esoteric meanings of the six-pointed star and its Electromagnetic Spectrum roots.Месяц назад
@Peter Givenbless Seems to be a twist on the old saying, "If a tree falls in the woods and there is nobody there, does it make a sound?" Thanks for your explanation.Месяц назад

As someone with dueteranomalous trichromatism ("red-green colour blindness") I can tell you that the colours you see sometimes differ from the ones I do; this is because all colour perception in humans is a result of how our visual system codifies different wavelengths of light, different animals also see different colours to humans, and not because those wavelengths have any objective colour themselves. In the absence of an observer there is nothing to distinguish one wavelength of electromagnetism from another save the frequency of the wavelength (which extends far beyond what is perceivable by humans).Месяц назад
