I address this dilemma to historians and anthropologists. Is it or is it not beneficial to colorize archival photographs using artificial intelligence? When I first discovered this possibility it all seemed beneficial, but after reading more I also saw ethical challenges. I am interested in the perspective of historians and anthropologists, and I am looking for further literature recommendations.
If you are properly citing your sources, you would have to mention that a photo was recolored, just as you'd mention cropping or any other work done after the fact (retouching, redevelopment).
As far as the use of such technologies at the source, in archives, it's pretty straight forward. As archivists, we would never recolor photographs (digitally or physically) in our possession and present them as the originals. This would go against pretty much all professional ethical guidelines, be it ICA or any national groups I know of. We are ment to preserve objects the way they came into our possession, both in physical form and relation to eachother, detailling any work we do that changes their nature. Recoloring to show the capabilities of modern technology and introduce new methods to our clients would be fine, but they'd be labelled as such and exist next to the original. Just how we often store the original binding of books, log the work done when restoring sigils down to the color pigment used or how we record the original order of documents if we had to separate them for any reason. People consulting our collections online or offline should be able to find out what work was done when, to which degree and why as well as know the original state an object was in when it came through our doors.
As far as recommendations for texts on ethics in archives go, the code of ethics of your countries archivist union/group should help you understand why this isn't exactly a dilemma for any professional archivist, or at least it shouldn't be. The ICA has published/aggregated a lot of different guidelines online.
As museum professional, I don't think AAM or any other national or international organization has released any guidelines on how to handle recolored photographs, but I think most museums would consider them a work unto themselves.
Colorized photographs are always a modern interpretation, and I think would be handled as essentially as such. They may be an interesting educational tool, but I'm not sure they add a great deal to the interpretation of historical photographs.
