Computer screens use red, green, and blue RGB as pixel colors, but why? They told us in kindergarten that RBY were the primary colors... #shorts #design #compsci
Eh I mean a teacher once told me cartoonists can't make it big. So that was a lie because how tf did Disney exist hahahhshwjje Ok stupid teachers aside thankfully she never lied to me about colour theory
Red yellow and blue are primary colors for artists. With them, you can produce all the colors you need to make a painting or drawing. If it’s just a joke, then why is the video so serious about it
The Isaac Newton Apple story is honestly a bit more interesting than “he saw something fall, let’s invent gravity.” It goes that Newton was under the apple tree on a WINDY day, and when an apple fell, he observed that it moved sideways AS it fell, leading him to hypothesize that, if something fell “sideways” fast enough, that it could outpace the downward pulling force and start circling the planet forever.
It's just a way to sum up everything from his research in a way children can understand. Which, is great and all, but we really shouldn't just leave it there.
@@roadkillpotato3468 the entire point of the comment is that the apple story as it’s most commonly told is one of those “lies to children” explanations.
Honestly, I haven't checked if it's true, but from what I know Einstein was the one to come up with the concept of orbit of "throwing something at x speed and at x height will make something orbit x planet" that was pretty much the new concept of Einstein's view of gravity that even included the distortion of space-time etc...
And also worth noting that in print, Cyan + Magenta = Blue, Cyan + Yellow = Green, Magenta + Yellow = Red. Vice versa for additive pixels. The primaries are the secondaries in the other system.
Of course! If: Green + Blue = Cyan; Blue + Red = Magenta; Red + Green = Yellow; Also: Red + Green + Blue = White; Then: (Magenta + Yellow) - White = Red; (Yellow + Cyan) - White = Green; (Cyan + Magenta) - White = Blue;
It's not exactly two different systems or anything. Colours in light works addictively. So two different coloured light (frequency is what decide the colour) will add up to get the mix colour and mixing all 3 primary will result in white- the mixture of all colours. But pigments work substractivly in the sense that a pigment is basically absorbing the colour it doesn't want to show, from light (usually sunlight) it is reflecting. So, mixing two pigments is basically removing more frequency from the light reflecting so eventually mixing all 3 together results in black- no light. And so in pigments, CMY are primary as each of them is abosorbing only one primary light colour Cyan-red Yellow-blue Magenta-green
Technically none of them are wrong, the tricolours are just for different things. Like with paint, you're dealing with pigments, and the primary colours for those are red, yellow and blue. For light, it's red, green and blue, and for printer ink, it's cyan, magenta and yellow. The primary colours are different for different circumstances and materials.
Well printers also work with pigments. For art it actually also would be cyan, magenta and yellow but people never changed it. You can try making one colour wheel with rby and one with mcy and you'll see that the colours are a lot more vibrant while they look a bit more "dirty" with rby.
@@kaylenvee8150 Well it's actually not different for them. They both have the same primary colours and are both additive colours since they're both pigments. It's just that back then it was very hard to get cyan or magenta while red and blue were definitely more popular. So when they experimented with colours to find the primary ones they came up with yellow, blue and red because of their limited resources. That's why you can also call it the traditional colour wheel. But mcy is actually a lot more accurate.
The reason why red, blue and yellow are introduced as the primary colors is that they are the primary colors of classical paint pallets. CMYK are pure primary colors but those colors were not achievable with pigments in classical painting. Both the cyan and magenta from CMYK were invented in the 1800s but color theory education precedes this.
And the Cyan was called Process Blue in the early days for printing, and the Magenta called Process Red. The yellow for print was also called Process Yellow to distinguish from the more traditional ocher yellows used in painting (mostly due to pigment availability, which is where all the RYB mess comes from as you mentioned). K was Key, black, and you got the white from the paper you were printing on.
I was once in a "last standing wins" competition where there was a question relating to primary colors. I got knocked out because I answered "red, green and blue".
@@justingolden21 or artistic, because the primary colors for paints are red, blue, and yellow... Edit: i don't know what i'm talking about, there is a better explanation below about paints and color mixing.
In computer graphics we studied that there are 2 methods: 1. Additive (RGB) 2. Subtractive. (CMYK). Additive methods are used for displays and CMY for printing colors on paper.
@@ethanalgicosathlonchannel1110 Yep, light and pigments do subtractive vs additive, so you have to use different color systems for different applications.
@@31redorange08 of course lol, it's just one of those things that I always asked myself but took for granted at the same time, and it felt nice to finally force myself to clear things up :)
Bruh red yellow and blue are still the main primary colors screen technology has nothing to do with it. They're called the primary colors cause you can't mix any colors together to get those 3. Screens don't mix anything together, they just render red, green, and blue pixels to make color display on the screen
i'm also brazilian and my art teachers taught me RBY (all of my art teachers) only later i noticed "wait theres RGB & RBY", now i say RBY when talking about art and RGB when talking about Light...
huehuehue é mais comum chamarem de padrão "CMYK": cyan, magenta, yellow e key. vcs já devem ter ouvido falar disso se precisaram mexer com impressão em gráfica
One of my favourite things I remember doing back when my parents still owned one of those thick ass TVs was getting my eye so close to the screen I could actually SEE the individual stripes of red, green and blue. I found it stupidly satisfying to be able to see that all colours on the TV comes from just 3 colours.
Newton figured out that white light was composed of seven colors of light, like on a Newton Disc. It wasn't until James Clerk Maxwell that we learned that RGB was all you needed to perceive white.
@@daschmitzi8403 you've missed the point. did you not read the second part? You only need RGB for humans to perceive white, because we can only detect those three colors. Newton understood white light was composed of different colors, Maxwell understood our eyes only detected three colors. In both cases, we perceive white.
Red is an additive primary. Cyan, magenta, and yellow are subtractive primaries. Since pigments like ink and paint "eat" color, rather than produce color, mixing them will mix the colors they subtract, rather than the colors they would add to become.
It’s different situations, in painting and stuff red blue and yellow are the primaries because they can’t be mixed from the other colours while yes in other cases cmy and rgb are the bases
You can actually easily make red and blue from other paints. Also, most artist won't use pure R or B, they will use Crimson for Red and Cerulean or Azure for blue, making it just CMY in disguise. Tell me how you do when you start using vermillion, indigo and yellow as your color palette, that's the true RYB.
@@xsana988 It's actually not harder to work with CMY, it's just that there's just a natural source of cyan pigment, and that's a specific butterfly's wings, and magenta pigment is a pain to extract. They were difficult to find in ancient times, so they made do with impure crimsons and azures.
No that's false. It's easy to make red using yellow and magenta. Same with blue. It's actually incredibly difficult to make a full color wheel even with regular paints using rby. If you mix red and blue you will not get actual purple you'll get a really sad grey-ish color. Magenta is needed to make real purple, so it makes sense. CMY are used in the painting world too. You can even make your own black mixing colors, it's much more rich and beautiful than tube paint black. And since you can make red, and blue, yellow is the only primary color of RBY. The true primaries, are CMY.
You can use any three colors as the three primary colors and you'll never be able to cover the whole specter of colors we humans can see anyways. However if you use cyan, magenta and yellow you'll cover a larger specter of colors we humans can see than if you use red, blue and yellow. However if you are a painter it would be silly to limit your self to only three colors.
Only in the additive color wheel, which is how anything light based works (like monitors). The subtractive color wheel (which is where the primary colors are red, blue, and yellow) adding all colors creates black.
@@FrogworfKnight Not correct. Subtractive color like paint does not combine color, it removes color. Also the primary subtractive colors are CMYK not RBY.
Reason for Red, Blue and Yellow is Red and Blue look similar enough to Magenta and Cyan that no one cared if those were the correct hues. Kids don't often know what Magenta and Cyan are. Also Red and Blue are easier to find in paints.
yeah because magenta isn’t a color in nature i think. so back then it WAS the primary colors but it definitely isn’t the truth for anything. not. even. paint…. ESPECIALLY PAINT. if you want a better purple you definitely aint getting that from red and blue in paint. it can work depending on the tones n stuff but it wont be that vibrant purple.
@@gamermapper cyan is no shade of blue. Saying cyan is a shade of blue is basically saying that yellow is a shade of green, since they have the same difference.
There are 2 sets of "primary colors" based on light or pigment. Adding all the colors of light results in the light being white. But adding all the colors of pigment results in the pigment being black. With pigments, you're actually adding colors that absorb specific wavelengths of light. If you add colors that absorb all light wavelengths, the result is black. But when you see light, you're seeing the color of the light itself (which is a portion of white light.) So when you add all the wavelengths of light, the result is light which is considered white.
@@DudeBroVideos Depends in which context : In art they are shades because they're used to create the illusion of lighting. In physics white is the reflection on an object of every wavelength of light while black is the absorption of every wavelength of light, thus neither are a color.
@@karma_yogi_42 Yes that's true, but at least we can assign a wavelength to red, or blue, or green, or yellow, you can't assign a single wavelength to black, or white, or purple for that matter, color is strange man
Yeah, I agree with the last one. Apple didn't fall on Issac Newton's head. Earth went up to catch the apple. This is the Einstein's general relativity which gives a modern explanation for gravity.
I think you don't need relativity for this. the Earth falls towards the apple under the third law (action and reaction) already. also, the no preferred frame of reference idea, in case you meant that, is special relativity
In kindergarten I had many discussions with friends on if the primary colors were red, blue and green, or red, blue, and yellow lol Later I found this out and blew all my friend's minds, I felt like a genius lol
I made a homework in elemantary school about main colors and while learning them i also learnt that the main colors for light are red green blue (RGB) and the main colors for colors (like painting etc.) are red yellow blue (RYB). A screen emits light so it uses RGB as main colors. It is very easy
The legend is that he was hit in the head with an apple, which gave him an epiphany that the weight of the apple and the force holding onto the moon were the same force. The truth is that he really did have an apple orchard where he lived, and he likely was outside in the garden watching apples fall when he had this realization, but that he didn't get hit in the head with an apple.
CMY was simply a subtractive model created by the Eagle Printing Ink Company. It is speculated that these were the easiest inks to create that could create rich colors. This means that it is just as much a primary subtactive (also known as reflective) color scheme as RYB as both can mix their respective base elements together to create colors of varying tones and shades. Neither is the "true" primary subtractive color scheme. (I have heard that CMYK cannot produce pure reds or blues but I have not researched this enough to backup this claim.) P.S. CMY and RBY are nearly the same base colors with different tones.
@@RonnygoBOOM CMY has saturation while RYB has vibrancy. It's all balanced depending on if you want darker or lighter colors. On a printing page, you want darker colors as these are absorbing onto a bright medium. Certain paints are much more likely to sit on top of the medium, on the other hand, meaning that RYB may be more conducive to that situation. The most ideal situation would be to use both.
the thing is, each of these color spaces (RGB, RBY, CMY) all have distinct limitations in emulating the full color spectrum we can see. also, most screens have a single uniform backlight, which highly limits the deepness of dark colors. so we cant even see the full true RGB spectrum available to us on most of the screens we use, because the darks can only get so dark, and not as dark as they actually can get in RGB color space.
I think you're the first channel and I think person on the internet I've seen actually properly explain the two different color wheels properly. I have had to do this so many times to people who argue the primary colors. Thank you, this was amazing to see
They didn't lie. There are two sets of primary colours: primary colours and primary pigment colours. Primary colours are Red, Green and Blue (RGB) and are mostly used in concern to light rays. Primary pigment colours are Red, Green and Yellow (RGY) and are used in concern with paint.
RYB was actually just invented because natiral Cyan pigment is extremely rare and natural Magenta pigment is extremely expensive, so they used the pigments that were available to them. With synthetic pigments we don't have that problem, so we can just use CMY, like normal people.
screen produce visible light to make images. printer receive light and make imagem of paint. red paint just reflex red light. if u blender all paints, this blender do not reflex any visible light.
With a lot of paint stores, they used Iron Oxide(Maroon), Black, and gold yellow to make paint colors. Black acts like a shaded blue, and the other two are self explanatory.
That’s false. Try making blue using only cyan and magenta. You can do that. Try making red using yellow and magenta. You can do that. Try making cyan using only red, blue, and yellow. No matter how hard you try, the best you’ll get is teal.
@@ethanalgicosathlonchannel1110 there are three sets of primary colors. Mixing paints and such will mean your primaries are red, yellow, and blue. Mixing light is additive, you have the primaries red, green, and blue. And subtractive, which is gonna be like printer ink and layered colors, the primaries are magenta, yellow, and cyan. Now read my original comment again and tell me I'm wrong
@@TheDeadOfNight37 pigments and dyes are also subtractive like printers. The primary colours are no different between inks and paints. Holdup let me get the link to prove it
i’m a stickler for definitions so when people say rby is PRIMARY (for paint???) makes no sense and i short-circuit. back then when magenta and cyan were hard to come by yeah! but now we can MIX much better and vibrant paint with cmy. i vividly remember wasting so much red and blue trying to get the right purple, it made me so mad.
Also, academia in general chose to hide the fact that Newton is more a mystic guy than a science guy. He spent more time studying things like ancient mystic hidden knowledge and occult studies than he does studying what we consider as pure science today. His magnum opus, the Principia, plainly shows influence of his mysticism, clear as day, if you're well versed in it, kinda like himself.
Mixing opaque pigment isn't the same as printing. In fact, it's really hard to get "true" colours using a cmyk process. It's generally "good enough" for most purposes. CMYK doesn't actually mix colours, but layers them, which is entirely different, thus the washed-out, off colour pigments. If you check a product box you'll often see a series of coloured dots. Those dots are used to align each individual ink that is used on the package. Some might be layered to expand the available colours, but they're almost never simply CMYK. You can't get a good red or blue from CMYK, you just can't. So each colour is a separate ink and mixtures tend to be half-tones. Plotter style prints might use 12 separate "true" colours to create their images. Really high end stuff might use a gigli process, printing each individual colour and shade using uniquely pigmented paint.
At first when I saw printer ink colours, I thought it was RYB (Red, Yellow, Blue). After a long time, I realise it was labeled as CMY (Cyan, Magenta, Yellow) Because a thick cyan looks really blue than a cyan and thick magenta looks really red, at that time. So now I know that the printer colour is actually CMY.
for new comers: actually there is 2 case. for anything related to electronic , rgb still holds true, but when it comes to physical color like printing color in paper or painting, your primary color is cmy
they didn't lie, they abstracted a topic to teach you a concept of mixing color. So that years later when some one makes a video about additive and subtractive color, you can understand it more easily.
i was always an intensely computer-first learner and i still struggle with mixing pigments because i've been working with light for my whole life and everything is backwards
The concept of primary colors is itself not a fundamental thing, it’s just convenient because it takes advantage of the response profiles of the three types of cones in your eye. You can define a color space with whatever colors you want, and they will all have different costs/benefits
This brings me back to the 5 years I had to study color theory, and we were taught for humans RYB are correct but how many darn differences there are in color wheels. Were super boring classes
Idk why, but I feel like if I were to watch this high it would make me feel something, so I’m gonna save it. Like, programming while high and researching deep stuff really gets me.
i once met a guy who didn't know the primary colors. i asked what yellow and blue together were and after several minutes his guess was teal. he wasn't homeschooled or anything, he's actually very smart, i just think he forgot. crazy stuff
Fucking hell, i learned this in my pyschology class man. Ppl were saying oh nah he got it wrong its red yellow blue and the teacher explained subtractive vs additive. Sick video
