Hmm,I’m sorry to hear that comic book colorists aren’t quite seen as artists.I’d also include the inkers but they’re a lot harder to define who is really good and who’s not,because they’re work is so dependent of the penciler.But I think the comic book colorists are becoming more n more important not only to the looks but also to the storytelling.And if that’s not enough,somebody tell me Jim Lee’s work has ever looked better before being colored by Alex Sinclair,in Batman:Hush.Another great example is Humberto Ramos colored by Edgar Delgado.Not to forget legendary Brian Haberlin and his Avalon Studios!Liquid inevitably springs to mind,also.But I guess I made my point so I’ll leave all the other great names for someone else to point.
As for other artists that I didn’t see named,I’d add(and really advise everybody to take a look at they’re work cuz it just rocks like crazy):
Marini-Rapaces
Juan Bobillo-Bird
Massimiliano Frezzato-I Custodi del Maser
Juanjo Guarnido-Blacksad
Barbucci and Canepa-Sky Doll
P.S.Still on the topic of the colorists,here’s a link to a great article about colorist/color artists:
