Has anyone seen a colour picker that gives you the ability to choose no colour? This is handy for giving users the option to choose, for example, fill colours for a square, where they may not want to choose a colour.
If you look at the fill colour picker in the Flash IDE, you'll know what I mean. I'm surprised this isn't an option in the default Flex component (unless I'm an idiot), and since a lot of the members of the ColorPicker in the framework are private...extending it is a pain!
