Setting the background with hexadecimal

i am kinda new with this flash programming, so i really need anyone’s help. in order to set the back by using this function ; SWFMovie->setbackground( int $red , int $green , int $blue ), only decimal numbers can be used in the function. but it is said that it can be set by using hexadecimal value. but when i tried putting in the hexa values, an error occured. there is nothing wrong when the value is set with decimal values. can anyone help me? please.:hang:
