I maybe in a complementary mood today but according to "google Ngram" the use of the word complementary is sliding (or is it not?), well in literary arenas that is. And apparently the word 'colour' is slowly on its way to becoming extinct. As always, the google Ngram appears to be an extremely reliable source for all your statistics queries.
