The point is communication, usability, and reproduction.
Communication because "Pantone 123" is easier to convey throughout the chain than "C:11,Y:22,M:33,K:44".
Usability because Pantone swatches are easier to use in a design environment, and also easier to choose the swatch number in Adobe than to mess around choosing "C:11,Y:22,M:33,K:44". You can also give your client a Pantone swatch book and let them loose without them having to know about CMYK, substrates etc. etc.
Reproduction because you can ensure you consistently achieve the same output irrespective of substrate (uncoated,coated,glossy, paper, fabric yada yada yada ...). It also gives printers a well defined reference for ink mixing, quality checks etc.
TL;DR: It makes everyone's life easier, clients, designers, printers etc.
Then the electronic measurement stuff was spun into Keysight and the Agilent was left with every other instrument stuff. So the soul of HP changed name twice
The HP also spun into HPE for servers/switches/storage and other datacenter stuff.
All to shed business units that are "just steadily making money" from ones that see bigger growth.
That dress seems to be doing just fine
Making all those samples is tougher to do with an open standard, you'd need some certification body/process for a company to make for people to use to satisfy a similar niche as Pantone.
If you get five printers and ask them all to print C:11,Y:22,M:33,K:44 you get five different colours as each will have to mix their cmyk inks to get that colour.
Pantone is a spot colour that means you can buy a pot of ink thats Pantone 123 there is no mixing so the colour is always the same. If you want to print on glossy paper thats going to change the look of the colour so Pantone also do inks for each surface you want to print on, they also do dyes for plastics and clothes etc.
Edit: The difference between the five printers would be insignificant but if you are a designer or want your logo to look exactly the same on stand ups, pamphlet, business cards etc you would use a spot colour.
As an individual crafter/designer I could see myself developing specifications for a small number of colors I use in a project. Doing 1000s of colors would be a huge project that would need some way to pay for it.
Anyone is still able to mix and use a colour through other means, but no one can put out a book with pantone’s same formulas.
The real problems however arise with trademarked colours (think tiffany’s blue, whiskas purple, kinder orange, etc.) That’s where you literally can’t use a colour in a particular copyright category.
Is it a problem, though? The only limitation is that you can't use these colors to misrepresent a product a product in a commercial setting. You can't sell an item wrapped in Tiffany's Blue.
" That’s where you literally can’t use a colour in a particular copyright category. "
No, these colors are not protected under copyright, only trademarks. The limits on using them only apply to particular context of trade. You can use trademarks freely as long as they're not misrepresenting the trade item. You can paint with them. They can appear in your photographs.
What you can't do is brand a product with them.
However contrary to your assumption; trademark protection is proactive or the owner risks losing their trademark to general use. This requires that even similar usage in other branding/trademarks is opposed.
For the Tiffany & Cp example, it means any kind of medium blue can't be used in their registered trademark categories regardless if it obvious that it's not Tiffany & Co. The benchmark for litigation is not misrepresentation.
This is a problem as there is currently a land grab for colours, and since each must be protected broadly, and each trademark owner files the broadest number of categories possible this becomes a minefield.
My point was only that it isn't a broad limitation such as Copyright creates that spills over into say, letting a camera take pictures with a shade of blue or using blue in a piece of software. I believe the scope of the trademark's application is fairly narrow, so it's not something most people in other fields need to worry about.
Did they patent every single proportion of paint mixture or what ?
edit: anybody who thinks the gamut of CMYK is anything like the gamut of Pantone, try printing out something purple on your printer. I worked prepress, and trying to get a good CMYK purple is my idea of hell.
And before any developers throw shade on this sort of obsessiveness, remember stones and glass houses.
Anyway the OP is about Pantome's databases, not the colors or their RGB descriptions themselves.
Not everything.[1]
