Ben—remember that the original article referenced in point #32 stated that it was useful to have a word for something with traits A and B if (A correlates with B) OR (A,B correlates with something else, C). So even though green eyes do not positively correlate with dark hair, the combination does correlate with your desire.
I know this is basically repeating what others have already said, but I just wanted to stress that A nd B do not have to correlate.
