Convert string to uint in actionscript / Flex

Question

I am creating a component and want to set the color property, as many flex controls do, let's say that I have a simple component, for example this, lets call it foo_label:

<mx:Canvas>
    <mx:Script>
        [Bindable] public var color:uint;
    </mx:Script>
    <mx:Label text="foobar" color="{color}" />
</mx:Canvas>

and then add the component to another mxml file, something like lines:

<foo:foo_label color="red" />

When compiling, the compiler complains: it is not possible to parse a value of type uint from the text 'red'. However, if I use a simple shortcut, I can do

<mx:Label text="foobar" color="red">

no problem, and the color property is still a uint type.

, , ? "" uint mx, , , , - ?

- utils:

    public static function convertUintToString( color:uint ):String {  
            return color.toString(16);  
    }  

    public static function convertStringToUint(value:String, mask:String):uint {  
            var colorString:String = "0x" + value;  
            var colorUint:uint = mx.core.Singleton.getInstance("mx.styles::IStyleManager2").getColorName( colorString );  

            return colorUint;  
    }
