I agree with you re: blue glass. I like that 1 Dalton went with dark grey glass (or whatever color you believe it to be. Some folks apparently think the JHT is green) rather than more blue, but I'm curious why "blue" or "mirrored" seem to be the only options embraced by developers when working with glass cladding (or grey, beige, brick-red, and brown for stone or panel cladding).
I'm not making the case for hot pink skyscrapers or aubergeine mid-rises, but there are other colors available to work with. How about a subtle green (like Parcel 12 ought to have been) or a peach/sunset hue here or there, maybe a tasteful splash of orange-ish?
