Pantone is forcing it.

Reply to ELI5: If time is the fourth dimension, then what force is pushing us through it? by quacduck
Assuming we treat time the same way we treat the other dimensions "force" is required. A force is only required to change the speed/direction you are moving.
And considering as far as we can tell everything moves forward at a speed of one second per second. With no change in direction or speed we shouldn't expect a "force" in the first place.
That said, time is already weird and screwy anyway so the question doesn't really work either.

So the science of color is actually pretty weird. It doesn't behave as simply as you think.
Color behaves differently depending on how it's made. For instance, mixing all the paint (pigment, subtractive) together will make black, but mixing all the light together (light, additive) will make white. Pantone deals with pigments, and RGB deals with light. They're so different that there some colors are only available in light (RGB) that don't exist in pigments (Pantone).
(Without getting too into it, that's actually why cartoons nowadays are so much more vibrant and brighter. Everything is now made with RGB tools for RGB screens, and we skip the pigment stage from when things were painted on paper.)
Think of it like asking why there isn't a direct conversion between gallons and pounds. They both seem to measure the same thing at a glance, but they're actually different.

Pantones are for print, they are specific mixed ink that creates a standard color that can be replicated on printed materials. Think the red in Coca Cola, or the blue from Tiffany. Those logos look the same when printed on any material, because a Pantone can be matched pretty much exactly. A Pantone is solid, where as CMYK is a mix of dots used to create continuous tone in print (if you look through a loop you can see the difference). Pantone is also a business, and has now hopped on the subscription train.

Time is a dimension that describes the progression of events. It is not a physical force that pushes us through it, but rather a concept that helps us understand and measure the passing of events.
The concept of time is fundamental to our understanding of the universe, and it is an important aspect of many physical laws and theories. However, the nature of time itself is still not fully understood and is a subject of ongoing research and debate in physics and other fields. Some theories, such as relativity, suggest that time is not a fixed, universal concept but rather a relative quantity that can be affected by the presence of matter and energy.
It's important to note that the concept of time as the fourth dimension is a purely human construct, used to describe the progression of events and to provide a frame of reference for understanding the world around us. The concept of time does not have a physical existence in the same way that other dimensions, such as length, width, and height, do.

Nothing needs to push us through time, we just are moving through it. An object in motion tends to stay in motion unless acted on by an outside force. The planets don't get pushed forward in their orbits, but they continue to go around their orbits.

Basically all of the above/whatever you have access to.
For production runs, ordering proofs of your work is very important before they run too many. You can make adjustments in a lot of different ways. But pantone is REALLY helpful so you and the printers have the same reference point for a color (theoretically).
I love this stuff, if you have any questions I'll ramble on about print production.

It is not a spacial dimension. Our movement through time works very differently from movement through space.
However, movement through space does not require a force. An object in motion stays in motion. If time did behave like a spacial dimension, then the only time any force would be pushing us through it is when we came in contact with something moving at a different speed.

Desktop printers and cheap bulk presses are CMYK, but a lot of industrial printing is spot-colour. If you’re printing advertising materials or signage or something, you load it with the exact colour inks you want in each area.

Having a widely supported standard is important.
Pantone is that standard, they have basically a monopoly on professional colour definitions. Everyone competent who is using colour professionally will understand a Pantone colour. Designers have lots of existing designs using Pantone colours. Manufacturers know how to produce all kinds of plastics, fabrics, paints, or anything else, to whatever Pantone colour you want.
Introducing a new standard would be very hard. All designs would need updating. All manufacturers would have to invest extra money in supporting it. Someone will have to produce the definitive colour samples that define the colours, and designers and manufacturers would have to buy them.
And there is little incentive for anyone to invest that time and money. The designers will still need Pantone to deal with the vast majority of manufacturers. The manufacturers will still need Pantone to deal with the vast majority of designers. It's extra cost for no benefit.

Fun fact: in the biz NTSC (US television, 24 fps, as opposed to PAL) is referred to as "Never The Same Color". It's a nightmare

But the person working on the colours needs a reference or they are just sending bad data to the manufacturers

This.
Pantone is basically so one person can say "I want this colour from this Swatch book and it needs to look exactly like this" and a printer operator 10 steps down the line can look at their pantone Swatch book and know they are matching to the same colour the original person is.
What Adobe displays on the screen is only a representation of that pantone colour in whatever colour space you are using. Monitor to monitor will vary and then actually printing will give another colour again.
There's no way computer software can display the exact pantone colour it is supposed to represent on every screen in the world accurately. Using pantone colours in illustrator, Photoshop etc. Is for reference. There is no CMYK or RGB value for any colour as that will vary across screens.
You would never go to a printer and say I need the colour on this logo to be c-14 m-45 y-89 k-20. You could but the result wouldn't be what you want. You could, however, use a pantone Swatch to find the closest possible match to what you want and ask them to print that, because then the printer can use their own pantone Swatch to match the colour when they print.

My understanding is that Adobe intends to start charging users to use Pantone color spaces.

Reply to comment by That-Soup3492 in ELI5: Why green and red are the definitive Christmas colors? by P4rturi
I agree with your perspective, but disagree with the assumption that the use is derogatory or a gotcha. I think it's usually used to indicate that an irreligious celebration is fine, because after all the traditions don't have their root in the religion anyway. At least, that is my viewpoint. I'm an atheist but I like celebrating Christmas as a secular holiday. Things like a Christmas tree don't feel weird because they're not Christian in origin anyway; there's no overt Christian symbolism going on. I would not ever set up a nativity scene, though; that would feel extremely weird to me because it's obviously an expression of a faith I do not have.
I believe the "gotcha" aspects are, in fact, a reaction to the "keep Christ in Christmas" people. There are people who believe that the secularization of the holiday is wrong and offensive. It's at that point that people are ready to come out swinging about how so many aspects of the celebration did not emerge from the religion itself. It's not so much a "gotcha" as an Uno reverse card. People aren't slagging on a holiday they probably enjoy themselves for being inauthentic, they're defending themselves against people who insist that the non-Christian aspects don't belong. And from what you've stated, I'm sure you agree that they do belong, because this is a cultural thing more than it is a religious one.

The idea of pantone is there is indeed a representation of that color in various color spaces, there is definitely a RGB value used to represent that pantone color. The idea of a pantone license is that people need to pay to say something is a pantone color.
I do not know this for a fact, it is only speculation -- but if the license ran out, Photoshop would probably be violating some intellectual property law by converting that pantone color to it's representation in RGB on a screen.

RGB doesn’t translate well to print media because print inks are ether Standard CMYK or Pantone. Commercial printer inks can reproduce a range of colors which can’t be 100% reproduced with RGB because RGB is more restricted. Look up “color spaces”.
I did a logo in Pantone coated ink and the client slashed the budget which required pivoting to standard CMYK inks. The brick red I chose came out as cherry red because those two reds don’t translate. The deep teal I picked came out as navy. This is the challenge of dealing with incompatible color spaces.

That's why you can buy the giant reference books from Pantone. They contain physical cards with color swatches on them and they make sure that every single color swatch they produce labeled "Pantone color <x>" matches every other "Pantone color <x>" in the world.
