Yes, I've been there, and been struck by the toy/disco vibes they gave off despite being an integral part of a beautifully laid out palace, which is why I posted on the subject, but it wouldn't be HN without someone who hasn't been there being contrary for the sake of it...
Shockingly, some of the windows look different from other windows and some of the colour combinations and pane shapes look better than others! They also have more effect when the light catches them directly. But yes, they're big plain panes of chunky glass (impressively big and impressively consistently plain at the time) which don't resemble the painted detail and tiny leaded panes of European churches at all, as I mentioned, and I suspect the author of TFA would be unimpressed.
