Interesting small rabbit-hole this AM in wondering why a ballet was called a "white ballet" (technically, in the original, a ballet staged in the white manner). As it turns out, at least per Gurgle AI, it is a reference to the white costumes, and indirectly to its classicism. The interesting thing about this is that "white goods" in this part of the world refers to large appliances -- glancing down that AI rabbit-hole as well, I learn that it is from the white enamel that defined expensive household goods in the middle of the last century, and that "brown goods" are rec-room wood-colored entertainment devices and "grey goods" are computers. Germany is apparently locally the source of the white enamel on appliances, with that industrialized technique dating from the late 19th c. I recall Hari Kunzru's recent Red Pill, where the writer visits a foundation in Germany funded by the estate of a chemist who had formulated a brilliant white for just that purpose.
Naming things in that manner is perhaps profoundly democratic, in the Deweyan manner. One of the oldest mosques here, dating from the 15th-16th c. had a madras nearby which was formally named after its benefactor, but according to a caption in the museum, everyone called it the place with the lead roof, in comparison to the timber roofs hereabouts (much later shifted to ceramic tile). Similarly, the fortresses overlooking the bend in the river (which must have been much larger in the past, as I can't imagine ships of any size navigating it) have formal names after their respective parts of the city, but are universally severally known by the color of the stone. The people talking about it came up with the name, according to the logic of their conversation. Sort of an unlikely Dewey/Habermas nexus there, perhaps.
