Talk:List of dyes

Anyone object to my compiling several on-line spreadsheets of dyes, C.I. numbers, Molecular formulas, and etc.? Maybe I will even find some CAS #'s? I have a list of 300, sorted A) alphabetically and B) by C.I. number, though some numbers appear to be duplicates when sorted using the latter method. It appears the Colour Index does this on purpose?

Ideally, I would print out the list and go double check it at the library, using "The Colour Index International", 1971.

Dunno what happened with Mr. Randall Meyer's table. I noticed this was an incomplete list so I took it upon myself to flesh it out. I've been including everything considered a "dye" and not just C.I. numbered dyes, and been careful not to add pigments according to the definition that pigments are insoluble in water. As I've researched, though, I've noticed that becomes a problem when it comes to vat dyes, as vat dyes are also insoluble in water and also considered pigments, yet still called and classified as "dyes." I may have accidentally left some pigments in the list as well.

I attempted to list only dyes that are frequently used, historically important, or have wikipedia articles of their own or at least have been mentioned in other articles. There are thousands of dyes classified that appear to have never actually been used but only catalogued. I felt it would be pointless to add them all, but what would the conditions really be to be in a "list of dyes"?

Several of the CI numbers contain typos but this is how they are consistently listed in several references. As much as I'd like to, it probably wouldn't be a good idea to pay for the actual registry and then share the proprietary data. EI at10s (talk) 14:56, 18 August 2022 (UTC)

Additionally, all the CI numbers, CAS numbers, synonyms and names for madder and its components are a jumbled mess in references and even between wikipedia articles. It's a headache that I'm not experienced enough to untangle. EI at10s (talk) 16:22, 19 August 2022 (UTC)
