Color Wheel Picker & Bucket Tools

Hey guys,
I am working on an app that will have a coloring book mode of sorts. Just wondering first of all if anyone has seen any code or anything around that created a color wheel picker for the user to choose colors? I have looked and can’t find anything. Second of all I am wondering if anyone has successfully made a bucket tool in corona. Just wondering how this has been or might be accomplished. In my case im using solid .png image files, so how could you code your app to determine black lines in an image and fill the area with color? Basically just wondering if anyone has come across any tools or code that deals with either of these two things, or if anyone has ideas of how either may be accomplished. Thanks so much.
