Berroco has two webpages for Trilogy:
the archived shade card page http://archive.berroco.com/shade_cards/trilogy_sh.html which inexplicably shows only a few colorways, and a second page that shows Sanguine (red) but not blue: http://www.berroco.com/yarns/trilogy

Yarndex has a more extensive collection of shade cards, beginning with Spring 2006 and ending with Fall 2009: http://www.yarndex.com/yarn.cfm?yarn_id=3630
