I know there are others out there who can't afford a $600+ program for a hobby and aren't willing to pirate, so I just wanted to share a few tips for those of you who are using older versions of Photoshop that don't have the ability to run actions or are incompatible with downloadable actions or who are using other programs, such as GIMP or PSP that either can't run actions or run a different format that isn't widely available. It's a bit more time consuming to recolor in GIMP because you have to go through the steps manually, as opposed to just pushing a button, but it's definitely doable.
