Hi, I'm in the process of creating an app and I want to include a color palette where the user can pick a color and apply the color to the background of an image (i.e. change the color of the walls of a furnished room). I've tried google for viable solutions to this but am stumped. Any ideas of how I can go about implementing this? I ran into the flood fill algorithm as a good way to implement this but I'm not sure how to yet. Any help is appreciated. Thanks in advance.
