Need some colour

This delicate flower looked rather uninspiring, so I put the image through a filter when I was editing it last night. Made it "pop" a little more. Photo was taken at the Reader Rock Garden on 13 August 2014. Is it a Campanula species?

The weather forecast is for snow this afternoon and, judging by the colour of the sky, the forecast is going to be right. I have a volunteer shift to go to, so the roads may not be too good on my way home. The temperature is only -4C (windchill -9C) this morning - could be a whole lot colder than that, so I won't complain.
