Steve Hamaker, who is coloring the new Bone color editions (link), has posted a couple of entries in his blog about how to color comics in photoshop.
His first entry, coloring with photoshop is a set of images showing the different steps from lineart to finished colored piece. He offers no explanations about each step, but it’s a nice start to see what he does to color the comics.
His second entry, more coloring stuff, though short, gives a few details of what he does to prepare the coloring in photoshop.
The comments of both entries offer some nice tips, too. I suggest you read them.
