I figured out what the "problem" is: when I draw a shape on stage, I have to break it apart(Command+B) then make it a symbol. If I don't break it and then make it a symbol, I get the color skew. Very strange.

//box is a movie clip placed on stage
box.addEventListener(MouseEvent.ROLL_OVER, rolyPoly);
box.addEventListener(MouseEvent.ROLL_OUT, skateAway);

//for some reason, the colors are darker – almost as if HydroTween is mixing in some black!!
function rolyPoly(color:String):void{
HydroTween.go(box, {color:0×99CC66}, .5, 0, Cubic.easeInOut)
}

function skateAway(color:String):void{
HydroTween.go(box, {color:0xFFFFFF}, .5, 0, Cubic.easeInOut)
}
//…but the color doesn't go to white!!

Regardless I made this change and commited it to the SVN. QueueLoader and QueueLoaderLite now support RaVeR cAsE

YOu are performng a match against file types (jpg, JPG) what if the fielname is: jPg???

try this:

var image_pattern=/(\.jpg|\.png|\.gif)\z/i
var swf_pattern=/\.swf\z/i

if (currItem.utl.match(image_pattern))!=null)_currType = FILE_IMAGE;
if (currItem.utl.match(swf_pattern))!=null)_currType = FILE_SWF;

the case is not an issue (/i)
filetypes can be any (\.extension)
and make sure it's at the end! (\z)

cause, your check will also say FILE_IMAGE for: a.jpg.swf

fun script nonetheless!
drop me a line!
