Color testing

hi,

How can I make a condition to test color like for example :
if I have a movie clip whose color is 0xff0000
and I wanna have a condition to test this like :
[AS]
//This is not the right way but how do I doit?
if(_root.MC.color == 0xff0000){
_root.Score = 100;
}else{
_root.Score = 0;
}
}
[/AS]
THANKS:)
