Why the hall is dark
The lighting is held at fifty lux — not for atmosphere, but as the limit for textile.
Light destroys dye irreversibly, and the accumulated dose never goes down. So for textile a limit lower than the usual museum level is kept.
Eyes adjust in about a minute, and there is a bench at the entrance for exactly that. The collector says some visitors complain about the darkness at first and stop noticing it by the end of the hall.
