[flexcoders] Fade from one color to another

[dorkie dork from dorktown]

I need to fade my application background color from 0xC47D31 to 0x67DEF9 and
I have no idea where to start. I've seen AS2 actionscript around that I can
try to convert but what I'm looking for is a already built MXML component
Effect, similar to mx:Fade or Dissolve.

I tried this and received errors:
   creationCompleteEffect="{fadeColor}">
   <mx:AnimateProperty id="fadeColor" property="backgroundColor"
toValue="#000000" target="{Application.application}" duration="5000"/>

ReferenceError: Error #1069: Property backgroundColor not found on
TestApplication and there is no default value.
   at mx.effects.effectClasses::AnimatePropertyInstance/::getCurrentValue()
