I always wanted to know why some artists use the blue pencil. And which do you use? Studying in animation I heard col erase is good because it's easily erasable. But why is it better than just drawing with plain hb pencil?
it's an organizational thing. You can scribble and build up the meat of your drawing loosely in blue and than go in tight with lead (or my case ink). If you do a lot of constructional stuff in lead by the time you're ready to go tight it's a grey mess. And I use the prismacolor blue lead in a mechanical pencil- [link]
