How would you go about taking a somewhat transparent overlay and replacing the colors of the underlying layers and exporting to many files? I saw how Photoshop has a "Pixel Replacement" feature but you need to supply it with jpgs to swap instead of color codes. I'd prefer just color codes so I wouldn't have to make a ton of images.

If you could point me in the right direction I would appreciate it.
