I'm not sure if this question has been answered or not, but for the record, I did a search for answers to my question.
But anyways, is there any way to highlight a section of a picture or, in my case, a .GIF drawing, and replace one color with another to eliminate having to go through and color every pixel individually? The drawings I work with, as mentioned earlier, are downloaded and published .GIF, but I edit them as .PNG's to eliminate the grainy look when saving the finished drawing, therefore, making it still able to edit.
If anyone could make suggestions or has a way to solve this, please let me know. It is greatly appreciated
