I feel that, for each show I've been doing, there's a character that dominates. Then in the next show it plays a smaller part, and then in the next it has a sort of cameo piece. So they all have their moment.
I use dull colors in my drawings because I started out using a root beer base, because it seemed like an interesting idea, and when it turned out that it worked quite well as an ink, I started using other colors that would complement it, like grays from Higgins black writing ink and, more recently, Dr. P.H. Martin's olive green and vermilion.
