I know that each era (as in decade

) has its colours, but the sterile grey, aluminum, putty grey colours and whites of this renovation will in my view hold up much better than the mauvy pinks puked up all over everything in the 80s

.
Seriously, though, there is a reason that trends tend to drift back towards more neutral or traditional colours over time. It's the time-specific trendiness at the ends of the arcs that grates over time.
It's easier to dress up a neutral colour with the trend of the day . . . adding orange or even some shades of blue or some shades of green accents to grey tones at some point in the future, for example. The main problem with the mauve explosion was that NOTHING actually went with it. It was an island onto itself as far as interior design options. Even natural wood didn't really fit with it.
That's the main reason I cringe when I see it. Any place that went whole hog on those colours in the 80s either is stamped with a period of time forever or has to basically pull it out and start over (as they just did at Canada Place).
Ending on a positive note, this renovation far exceeds any expectation I had. I think it looks awesome, and I'm so impressed with how it fits with the new convention centre wing. I love the integration of sophisticated woods in the design as well. It can't compete in that regard with the new centre, but they do a good job of bringing pieces of that look into the renovated space.
