To my knowledge, there is actually a pretty important additional reason why black is necessary: Our Cyan, Magenta, and Yellow inks are imperfect, and combining them can't actually quite reach black on their own.
Yup, also why fancier printing processes will have more inks to get closer to the desired colors. E.g. home inkjet printers can have 10 tanks, and professional printers will mix up specific colors to match the brand's colors.
@@Dustmix they're obviously more expensive than a conventional CMYK inkjet, hence not much consumer interest. compared to industrial machines that take up a large room though they're not much larger than a conventional printer
And there's different K's as well. K is also used to not oversaturate the medium you print on, because things can only take up so much ink. Newspaper for example can't take up much at all, while thicker paper can usually take up a good bit more, and then you can add a bit of CMY to get a darker black.
Also RGBW does exist. If you are searching for more efficient LEDs you'll probably find them. They use a white LED in the same way black is used with cmyk. It's pretty cool!
They also tend to produce white light better than standard RGB. RGB LEDs by themselves, especially cheaper ones, tend to produce a white with a blue tinge, because blue LEDs tend to be the brightest. If you have a white LED, then you can produce a proper pure white.

@@kelpgaming6995 cyan and magenta are their own separate hues from blue and red though, and their distinction from ryb lets cmyk more accurately represent a wider range of colors.
I read that ink isn't purely subtractive. It's somewhere between subtractive and averaging mixing. So mixing cmy will just give you a dark gray or brown but not black. It's because some light just hits the surface of the ink and bounces immediately back without getting both sets of frequencies absorbed by both pigments.
That's also true for RGB devices as the spectrum given off isn't a specific set of 3 wavelengths, but rather 3 ranges. That creates issues when mixing and throws off the color. This is why displays have to be calibrated and the rgb values you send to the screen get gamma corrected before they are displayed.
This video explains something in the most intuitive way i have seen for any video ever. I can't explain how satisfying it felt watching this video just because of it being explained so simply. Well done.
Some applications of RGB light actually do have the additional White channel - see for example all decent-good RGB smart bulbs. They have this extra white channel as colored LEDs are usually significantly more dim than white ones, so the extra White LED can turn on to boost the brightness when applicable.
This feels like a revalation i just randomly found this video and everything just made sense and i love the color coordinates XYZ for CMY and K is just all units to 1 moving it diagonal. and how it's effective in a real world senario of printing. never owned a printer but damn does it make me want one after this video.

This is one of the best explanations of a concept that I have ever seen. Just something about using a minecraft/voxel model that works mathematically and visually is so pleasing and simple.
this is such a genius way to visualize color space and CMYK and ink volume! I'm almost imagining some redstone shenanigans that retract three CMY blocks and push out a black cube XD
I would also add that in practice, widout the black ink, you can't really achieve a black colour by mixing the other ones, you get a dark grey. That's because when you mix inks, the particles or each of them occupy space that isn't absorbing the other colours.
@@The14Some1 Red Green Blue White It has a “white” so it can have brighter colours/tones instead of K (key/toner) which basically means “dimmer” to make the colour more dark. Key makes sense though.

So cool to see color theory taught in minecraft- and it makes so much more sense than it did before! funnily enough, there's an application in minecraft for color blending along pretty similar lines using glass, and i wonder if it works the same way with CMYK. will mess around with it for sure! ...update, thanks to colors having unqual priorities, it doesn't work. would have been cool though! some aspects probably still hold true.
Correct me if I'm wrong, but I think we don't actually save the amount of ink we're using, but rather the amount of coloured (more expensive) ink. I would imagine that, for every coloured "dot" on the paper, we use the same amount of ink but to achieve different colours we're just changing the composition of the ink we're using.
That, though, doesn't take away from the video. I actually don't know how it works and didn't understand CYMK before this, so thank you so much for this simple and concise explanation!
Hey Gneiss i hope you see this, i think you would LOVE the Create mod, i would definitely recommend trying it out (i know it untelated but i wanted to put this on your most recent video for you to see this), btw i love your videos, amazing youtuber!

@gneissname dont worry take your time, i just thought it would be something you could have fun with, have a wonderful day and i hope you can take care of that backlog XD
Wouldn't replacing the 6 CMY units with 2 K units result in a less dark colour? Since mixing 6 CMY irl makes 6 K, there is no loss of matter. If we replace that with only 2 K, the ratio will change, resulting in a lighter mix. I think it's more because black ink is usually far cheaper than colored. It would cost less to get originally black ink than to make it yourself by mixing colours.
I feel like this video shouldn't have "Minecraft" in its title. It's got nothing to do with it, and explains the subtractive color-space pretty well in the context of printers.
Wouldn't you just scale all ink volumes to reach the necessary volume? The color os only defined by the proportion of each component inside it. You can make half as much of the dinal color by using half as much of every component. I'm a little confused now because in digital colors, half of each component results in a way darker color...
Ah yeah, the Red-yellow-blue colour system you learned in kindergarten and used all the way through school and for your entire life so far is completely wrong btw. Red and blue aren't even primary colours with paint mixing, they're secondary because red can be made my mixing magenta and yellow, and blue can be made by mixing cyan and magenta.
One thing I'm wondering is how to get the Gamut shape of CMYK in the chromaticity diagram. For additive models, it's obvious - it's just the polygon spanned by the primary colors. But CMYK is a hexagon, and I can't find anything about how to calculate the positions of the three vertices that aren't cyan, magenta, and yellow.
So I assume the way you would calculate the conversion from CMY to CMYK is by finding the smallest value out of CMY then subtracting that value from all 3 of the values and setting K to the value?
Did you know that CMY are actually the primary colors and not RBY? That's because it was easy to mistake Cyan and Magenta for Blue and Red. I don't understand why people think CMYK can *only* be used for printers! I mean, it's not like Canon has a trademark on what colors you can use for artwork! Also, CMY makes more sense than RBY anyway because Yellow is too close to Red to count, and Red and Blue are additive colors, meaning using them as primary colors only works when it's a direct light source and not just reflected light like when your dealing with CMY! I can elaborate, but I feel like I should put up the website I found this info on because it’s easier than explaining in a comment, because it would have to be 3 paragraphs long for me to fill some of the holes I’m seeing in this comment. Edit: ok I types this before watching the video because I assumed you didn’t know. Ignorant of me, I know, it’s just I’m baffled that when I tell people this, they find it so hard to believe, not only that, but I’m baffled that this info isn’t more widespread! I mean this _should_ be taught in schools and art-classes! But it’s not! They just say “use Red, Blue and Yellow” instead of the right ones!!! You know I only knew CMY were actually primary three-four years after being homeschooled from 9 years old! Unbelievable, my mind felt like it filled a question I forgot I was asking for so long…
I would like to do a video on color that actually talks about the wavelengths of color the eyes can detect and kind of get into the whys of color sometime.
I'm pretty sure Blue and Red are considered primary colors, and Yellow is considered a secondary color. The other primary and secondaries are what complete "RGB" and "CMY" (Green, and Cyan and Magenta respectively) Granted, this is _specifically_ for most trichromats. I'm pretty sure that there are some people who you could say have yellow as a primary color, either alongside red and green, or instead of one or even both of them. This is dependent on the exact set of cones someone has in their retina. Edit: Huh. I was honestly surprised to see Red Blue and Yellow in the image previews when searching up primary colors. Seems it _was_ used for a while. Also the terms "primary" and "secondary" color seem to be specific to the color space you're using, so CMY are considered primary colors for the subtractive model, but secondary colors for the additive model.
@@angeldude101 interesting how you never knew that people thought RBY were primary colours. I mean it’s on Microsoft, Google, Xbox and more stuff! Whatever you were taught at school, it was certainly more up to date than ours! 😂
@@alex.g7317 It's been years since I would've been taught that at school, so maybe I was taught RYB back then and just forgot. On the other hand, I'm a nerd and color for me comes up more in the context of biology, light, and computing. The first is *roughly* RGB, the second a continuous spectrum, and the last 24 or 32 bit RGB(A), CMY(K), and HS(V/B). "Red" for me means #FF0000 or ~700nm electromagnetic radiation.
Sorry if this is an ignorant question, but if that color is 4 parts Cyan, 2 parts yellow, and 2 parts black, can't you divide them all by 2 and get the same color? 2 parts cyan, 1 part yellow, 1 part black? why does that give us a different color on the 3D color space?
Good question and I think I have an OK explanation. You would get the same ratio of colors and it would be the same hue but it would be different tint. This specific color we are making is for a specific area. If we have less paint but still need to cover the same area, and we are assuming a white background, there will be less coverage and the color will be lighter. If we think about it from the RGB color space have you have 50% of red green and blue, you get middle grey, if you divided it by 5 you will have the same ratio and color, its just darker.
CMYK is so finicky. I've recently printed books for a Typography and Visual Communication class at my Uni, and the amount of trial and error, slight tweaking of the colours in InDesign and Illustrator I've had to do, just to reach the pantone colours I wanted (I was aiming to achieve the same colour as my department has) was astounding. Best thing is I straight up asked my professor what values are in this specific yellow and she told me - 100% yellow and 20% magenta. It did not match even in the slightest. It did on my final presentation boards first try, but that combination of paper and printer that was used to dish out the books just did not go hand in hand. CMYK is a mess
I'd always heard that it wasn't possible to get all the way to a deep black using just CMY. From the pigment-quantity perspective you show, would it be accurate to say that there's a physical limit to how much pigment you can get in a single spot, and that getting to deep black with CMY would require pigment than that limit?
Yeah a bit but its its probably a pigment limitation too. The perfect number model and real life usually doesn't work out. There is a well known saying in geology at least: All models are wrong, but some are useful.
if you did CMYRGBK, you could save even more ink by compressing C+M into B, M+Y into R, and Y+C into G. is this not done because it just ends up being too complicated, too many different types of ink?
Yeah, you can definitely add more colors into the mix, I have a large format plotter at work that uses 6 colors and I know HP makes one that uses 10 cartridges.
@@gneissname ah, so it's done but it's just fancy lol i'd imagine it increases the accessibility of highly saturated colors as well, in addition to using less ink
To my knowledge, there is actually a pretty important additional reason why black is necessary: Our Cyan, Magenta, and Yellow inks are imperfect, and combining them can't actually quite reach black on their own.

It did on my final presentation boards first try, but that combination of paper and printer that was used to dish out the books just did not go hand in hand. CMYK is a mess
oh thank god u fixed the magenta that was rlly annoying me
I’m sorry for the discomfort 😀
Can you do one on XYZ, Lan, Luv and Lch?
Also, isn't black ink cheaper?
Cool vid
I'd always heard that it wasn't possible to get all the way to a deep black using just CMY. From the pigment-quantity perspective you show, would it be accurate to say that there's a physical limit to how much pigment you can get in a single spot, and that getting to deep black with CMY would require pigment than that limit?
Yeah a bit but its its probably a pigment limitation too. The perfect number model and real life usually doesn't work out. There is a well known saying in geology at least: All models are wrong, but some are useful.
Cool!
wow... nice vid!

2:47 isnt it "two thirds"???
-_-; yes.
What about LAB color space? 🤔
I'll be working on the Oklab color space next. Its going to take a while. Need to make some visualizations for "why lab" and it should be pretty cool.
if you did CMYRGBK, you could save even more ink by compressing C+M into B, M+Y into R, and Y+C into G. is this not done because it just ends up being too complicated, too many different types of ink?
Yeah, you can definitely add more colors into the mix, I have a large format plotter at work that uses 6 colors and I know HP makes one that uses 10 cartridges.
@@gneissname ah, so it's done but it's just fancy lol
i'd imagine it increases the accessibility of highly saturated colors as well, in addition to using less ink
@@rarebeeph1783 Yeah, the added colors are usually vibrant or matte varieties.
hi what mod did you use for colors? thanks!
No mod, I made custom resource packs for this one. None of my videos use any visual mobs.
use glass and RTX
