Wall Paint Visualizer

I need a Flash project file with the source .as script, the Flash Movie needs to be a visualizer for how paint colors will look on a wall. The user will need to upload a JPG file, then the user will select the colour to replace ( which will be the color of the wall at present ) and select a colour to replace with. The movie must then render the image with the new colour. There must be a setting (scroller) to set the level of similarity to match the pictures color. Also light tones need to be considered, light falls randomly so colors will be brighter in some spots, and darker in others. See ColorJive for an example.
