alt Hacker NewsI still don't understand is why they don't even make an attempt to apply overlayers, when (as the author notes) there is ample secondary evidence that it would be present. It's not like there isn't already some element of inference and "filling in the blanks" when reconstructing how something was painted from the scant traces of paint that survived.
This is somewhat an unfounded theory of mine and I was hoping if anyone has any insight: but I sense that this is perhaps a construction of Western restoration/preservationist theory. A lot of effort seems to be taken to either preserve original material, not take liberties etc. While touring temples and museums in Japan, I got a sense that restorations were much more aggressive, and less regard was taken to the preservation of material (or building "fabric"), with a greater focus on the use of traditional techniques during restoration.
