Well, most of the options in the adjust color menu will allow you to change color, though for what you're doing the HSL adjust is probably the best. As for doing a bunch at a time, the HSL saves its settings between use, so if you got a copy of good old macro recorder from win 3.1 handy, you could try opening all the files by dragging them in and set up a keystroke only macro that goes to HSL (Shift-H), hits enter, followed by save (Ctrl-S), then closes the file (Ctrl-F4). Set it to repeat and and wait for all the images to close. Other than that, I don't know of a fast way to do this on a batch of images, furthermore, the last time I used macro recorder was on 95, not sure if it works on whatever you're using.

Hope that helps
