In fairness, the Liberals did change the black on yellow plates to red on white, the Liberal party colours, in 2007. They also added a french slogan to the blue and white plates in 2008.

Additionally, the previous blue on white design was really on the NDP. The Conservatives' only contribution to the design was accommodating the seventh character when valid six character combinations ran out.
