Although in MXML and CSS source code you can specify a color in the format #D3D3D3, at runtime Flex components dealing with colors generally represent them as RGB unsigned integers like 0xD3D3D3, not as strings like "#D3D3D3". We probably should have provided better conversion routines between the two representations, but I don't think we expected developers to need to do this. We assumed that user interfaces would present a ColorPicker, not a TextInput for typing in a string like "#D3D3D3", and that databases would store a uint, not a String, because this is more efficient. Please file an ECR and get people to vote for it if you feel that this is a significant deficiency in Flex.

Right, it does have a text box, with the color in Hex notation, so you'd assume that there'd be a real easy way, in ActionScript, to pass a hex value to it, but there isn't.
