Yes, sorry, you are completely right. These were just the bookmarks from my "Art" collection of bookmarks, not the "Photography" department:

https://www.imagepermanenceinstitute.org/

But since we were also talking pure pigments, I thought the other links potentially very useful as well, and maybe in some ways even more relevant in that context.
