What a treasure! I particularly like one thing about the picture of the butterfly. Look up what’s wrong with nearly every modern depiction of butterflies if you dare…
Google gave me nothing
Interestingly, neither the web page nor the previous threads address that the colors in the book might have changed/faded over the centuries, depending on the dyes used. The pages probably didn’t get significant light exposure, but heat and chemical factors might have had an impact. And, of course, the photos might not be completely color-accurate.

When I wrote my thesis, it was supposed to be on acid-free paper and archival, but I snuck in some color printed pictures, and boy did that not work out so well. 20 years later and the pages are yellow and the colors are fading. > the photos might not be completely color-accurate It’…
That's back far enough that following the recipes is bound to be _hard_.
Chemicals and pigments and such go by different names, are produced in different processes and formulations, and some are extremely hard to get due to someone noticing that it rots your genes or whatever.
Maybe whatever pigments are used in watercolors aren't affected by this much, but I bet at least some are.
It'd should be fun to try though, for a certain kind of person.

You don't need a license to use any color in Photoshop. You need a license for a collection of stand-in mappings for spot colors, the vast majority of which can't be convincingly represented on a monitor. You can ignore Pantone entirely, put in whatever color you want, and nobody will know or complain. You can even use any color you want in Photoshop, then make a plate out of it for the press, and tell people the Pan…
There is a useful service Pantone is providing: when I want a physical thing to be a certain color, I can buy that color ink from them to get it consistently. But once I've applied the ink to the thing in question, it's mine like that forever. Imagine that Pantone demanded all of their customers to pay them protection money every month, or they'd send their goons to spray-paint black over everything you ever used the…

maybe the interesting aspect is the perseverance of the author and their systematic and thorough approach and their desire to create a complete work over all watercolor pigments?

Is the world better off than if we just eyeballed it?

So basically, they want some money to map RGB values to a set of numbers, each of which enumerates the output of a ridiculously challenging chemistry project?
> they want some money to map RGB values to a set of numbers Sorry to reiterate this in another thread, but what they want is some money to map the output of a ridiculously challenging chemistry project to some RGB values that will give a vaguely similar impression.
Though that would be failing to leverage dominant market position to extract maximum value. Leaving aside the "nice years of images you'all have there... it would be a shame if..." aspect of current events. To be fair, it's not like some (Si not color) chip makers with dominant position aren't "here's the spec... and if you want to actually use the chip, without massive reverse engineering, ask sales about your support and partnership options". And I suppose there's also "surprise, v2 is discontinued - to adapt your work to v3, contact sales".
I'm exploring emphasizing spectra in K-2 color content, to help disentangle the usual incoherent blur of material properties, physical light, and physiologic color. So I've wondered the last few days if Pantone somehow prevents scanning a chip set and posting spectra. As it might also permit "New Dryadtone(tm pending) Adobe palette to the rescue, now for only $5/mo! With our wonderful Palette Pricing Stability Guarantee!"

There are some pigments we wouldn't use anymore like ground up mummies for yellow.
What a strange world.
Any link to access the book ?
