Last year, Liberal MP Carolyn Bennett suggested that there's been a pattern to this.

"It's the branding of the websites and how blue is everywhere now and all this subliminal messaging," she told the Huffington Post.

"I mean to the point that they have gotten rid of all the red and green lights at Christmas time and we have blue and orange lights. What's with blue and orange Christmas lights all over Parliament Hill? There has been a serious effort in rebranding Canada blue."
