August rain could dull fall colours

Researchers say the impact of unusual summer weather that brought wildfires in some parts and heavy rain in others is being seen in the fall colours this year.
In areas where August saw heavy rainfall, dull brown has replaced the vibrant oranges and reds usually seen this time of year.
Dalhousie University professor Mason MacDonald says when there is not enough sun for leaves to produce a certain natural pigment, the impact is evident in the fall colours.
