Why doesn't colour scheme representing this city matter? The blue and green is without a doubt the best colour scheme this team has had, from a design profession stand point, from a heritage stand point, from a marketing standpoint, etc. Believe it or not, but embodied meaning in design has significant value. Besides, like the other posters noted; black, red, yellow is simply overdone and boring.
On another note, I've made my disdain for the skate logo known before, but I'll re-iterate; it as a logo has no merits other than the nostalgia attached to it. It's gaudy 80's laser motif is a played out, busy, muddled and a gaudy disaster in this day and age. We need a logo that is timeless and simple like the Habs' logo, the stick and rink may be a bit boring but it's also timeless and unique.
