I just read your profile which I hadn't before I commented - and so I see you know me :-) :-)
Just a note by the way - yes, I wanted the genders for each color to be something each person can work with as suits them - to see a Lady instead of a Lord Silver is just as valid. To see Silver as a silver bird is just as valid. I give them form, but want the readers to find their own best and closest connection.
