Is it a black and white scan of a coloured publication, or is the original publication black and white too? Looking e.g. at Page:UKSI19810859.pdf/64 where the sign "End of prohibition of goods vehicles…" is black and not grey in the original publication, I would say that the original publication was not coloured either. If so, then we should not insert coloured pictures into it. --Jan Kameníček (talk) 19:55, 26 November 2021 (UTC)
- This is a black and white scan of a color publication. I've seen an alternate scan (I can't put on Wikisource) and the diagrams are in Color.)ShakespeareFan00 (talk) 14:58, 30 November 2021 (UTC)
