To be fair, that green glass is all South Core in the background, most of the newer development in the St. Lawrence Market neighbourhood uses a good mix of colour and materials.
... and there are tonal variations - and colour variations - in the buildings shown in the images that Razz has posted. Tonal variation is, by definition, not "monotony" .... even when the range is similar. And why shouldn't there be a unifying look, tying together buildings that serve essentially the same purpose?
