Green with envy

Is there any other colour that this party could use? It absolutely has to be green.

And green has all sorts of other associations that are both positive and also fit with the goals of the party; fresh, growing, environmental, trees, plants, etc.

While not as popular as some colours used by brands, green is popular with brands that have an environmental slant, or want to be perceived that way.

But it is also the colour associated with one of the seven deadly sins, envy. But I think that the Green Party would like Canada's environmental record to be the envy of the world. Perhaps not a bad position to aim for.
