Trying to design a flash colour chooser

I’m just about to finish something up thats partially flash. However, I need to design a colour chooser (rather like the one thats already in in the flash publisher), but as part of the flash product/animation.

Does anyone know of an example of where this has been done before, I would like to have a look at an example before embarking on it, or get some ideas of the best way of designing this

(movie clip >> opens out to many colour buttons >> onClick upDate textField with the hex code?)
