AS3 Color (TextFormat)

I am applying a color (white) to a field in a class. Simple enough.

white = new TextFormat();
white.color = 0xFFFFFF;

Now later on, I flip through the DisplayObject looking for that value. I never find it, but tracing shows me what value I should be looking for.

var nCount:Number = container.numChildren;
for ( var i:Number = 0; i < nCount; i++ )
{
    var curSprite = container.getChildAt( i );
    trace( i, curSprite.label_txt.getTextFormat().color );
    ...

So what gets traced? The value: 16777215. I am assuming that 2 extra digits in there are translations of the alpha value. However, it still seems a little strange... but I am no mathematician or color theorist. I'm sure its correct, and I know what to look for, but I don't know exactly why yet ;) Magic numbers to me at the moment.
