Hi, Tim.
Thanks for the advise. Though, it didn't help. Even calling
super.invalidateDisplayList() I get no color change.

Hi Roman,
After you conditionally change the color, you have to redraw the
itemRenderer. Try this:
[Bindable] public var highlightColor : uint = 0x000000;
public override function set data(value : Object) : void
{
super.data = value;
if (value != null)
{
if (!value.valid) highlightColor = 0xFF0000;
}
super.invalidateDisplayList();
}
<mx:Label color="{highlightColor}"/>
