Administrator Conduct Case 2024-1: Mzajac opened[edit]

You recently offered a statement in a request for arbitration. The Arbitration Committee has accepted that request for arbitration and an arbitration case has been opened at Wikipedia:Arbitration/Requests/Case/Administrator Conduct Case 2024-1: Mzajac. Evidence that you wish the arbitrators to consider should be added to the evidence subpage, at Wikipedia:Arbitration/Requests/Case/Administrator Conduct Case 2024-1: Mzajac/Evidence. Please add your evidence by January 30, 2024, which is when the evidence phase closes. You can also contribute to the case workshop subpage, Wikipedia:Arbitration/Requests/Case/Administrator Conduct Case 2024-1: Mzajac/Workshop. For a guide to the arbitration process, see Wikipedia:Arbitration/Guide to arbitration. For the Arbitration Committee, Dreamy Jazz talk to me | my contributions 17:55, 16 January 2024 (UTC)[reply]

Faded or drifted Pigments in scanned documents.[edit]

A number of scanned works have been uploaded on Commons, including "Atlas of the Munsell Color System" (1912). This included a set of color charts. However, the colors in the chart may have faded compared to how the originals appeared. The Munusell system was analysed in the 1940's and a set of xyY data exists, which means it might be possible to recalibrate the charts. What I am asking about here (rather on the Refdesk) is whether there have been any Chemistry journal articles on which pigments (especially early 20th century ones) are likely to be subject to color drift, and potentially by how much. Coloimetric data is unlikely to exist for pre 20th century works however. ShakespeareFan00 (talk) 22:47, 18 February 2024 (UTC)[reply]

Hello @ShakespeareFan00: - there are a significant number of journal articles about pigment changes, the Royal Society of Chemistry have a library, from memory, of pigments and dyes. We should be able to determine the original colours by following the original recipes though, since the colour will be a function of the chemistry, and that being the case, I'd be shocked if there's not an old Munsel colour system to Pantone conversion chart somewhere. Nick (talk) 00:03, 19 February 2024 (UTC)[reply]
Thanks. The pointer to the Royal Chemistry Society Library was all that was needed, you don't need to do anything else on this.
There is a conversion from Munsell into xyY space, that was published in the Journal of the American Optical Society around 1940, which someone was transcribing at Wikisource.
By comparison of the expected RGB triplets from conversion of those xyY values, ( possibly allowing for a change of illuminant), it should also be possible to compare the drift in the scan against known standards. Other considerations include potential concerns about gamut conversion truncations ( sRGB doesn't cover all 'print' colors for example.)
Atlas of the Munsell Color System: co:File:Atlas of the Munsell color system.djvu
A tristimulus specfication of this appears to have been published as : Tyler & Hardy, (1940) "Analysis of the Original Munsell Color System" in Journal of the Optical Society of America v. 30 iss. 12, pp.587-590.
Obviously, if I go further, I'll need to do a fuller literature review, so thanks for the appreciated pointers given :) ShakespeareFan00 (talk) 08:26, 19 February 2024 (UTC)[reply]
@ShakespeareFan00: if you're needing any literature on this that isn't digitised and online, or which isn't available through any of the Wikipedia Library avenues, you can see if the Queen's University Belfast library has a print copy https://www.qub.ac.uk/lib/ and I'll get one of our librarians to scan it for me - likewise for anything on the Royal Society of Chemistry side, I can request material from them if needed.

Tfm notice on Template:If both[edit]

Could you consider using ((subst:tfm|help=off|type=disabled|1=Both)) instead of removing the whole notice? Per the TfD process, the notice should stay there. Nickps (talk) 11:51, 8 June 2024 (UTC)[reply]

@Nickps: is that going to break the template again, as per the last notice you asked be placed there ? Nick (talk) 11:53, 8 June 2024 (UTC)[reply]
It shouldn't, considering that, per the documentation, it outputs nothing at all on transclusions. Nickps (talk) 11:55, 8 June 2024 (UTC)[reply]
If even that fails, then wrap it in <noinclude></noinclude>. But not including it at all is not really an option. Nickps (talk) 11:56, 8 June 2024 (UTC)[reply]
Also, more out of curiosity than anything, how did the template break? Nickps (talk) 11:58, 8 June 2024 (UTC)[reply]
It was causing any infobox with the ((Marriage)) template to throw up the following error <div style="display:inline-block;Expression error: Unexpected < operator">​. The alternative TfD does look to be working correctly now (having purged and checked with pages showing the error previously). Nick (talk) 12:12, 8 June 2024 (UTC)[reply]
@Nickps: I'm a bit worried that you're more concerned about the TfD template than the functionality the If both template is providing and can't provide a suitable reassurance your requested edits aren't going to break the template. Again. In any case, we will give it a go and see what we can do. The TfD template doesn't really need to be there now, does it, likely nobody will comment at the TfD and it'll be closed as merge in a week anyway, as it's an uncontoversial merger. Nick (talk) 12:01, 8 June 2024 (UTC)[reply]
Let me phrase it better then. I'm 100% confident that using <noinclude></noinclude> will result in absolutely no breakage. There's your suitable reassurance. I don't agree that the template doesn't need to be there since people may contest the close by arguing they didn't know about the TfD. Nickps (talk) 12:05, 8 June 2024 (UTC)[reply]
I doubt anybody will contest anything, because nobody cares anymore. Nick (talk) 12:12, 8 June 2024 (UTC)[reply]
