im trying to use a parameter to change the bg color
setBackground(Color.black);
so i could have it like this setBackground(Color.grab_bgcolor ); but i dont know how to do this either really i was just going to use a switch case statement then figure it out but i cant even get the parameter in

getParameter() returns a String, not an int, so you need to parse the string to turn it into an int. Probably the easiest way to define the color is to use RGB components:int    bgColor_red = 0;
int    bgColor_green= 0;
int    bgColor_blue = 0;
String bgColor_redString = null;
String bgColor_greenString = null;
String bgColor_blueString = null;
bgColor_redString = getParameter(bg_red);
bgColor_greenString = getParameter(bg_green);
bgColor_blueString = getParameter(bg_blue);
try{
    bgColor_red = Integer.parseInt(bgColor_redString );
    bgColor_green= Integer.parseInt(bgColor_greenString );
    bgColor_blue = Integer.parseInt(bgColor_blueString );
}catch(Exception e){
    //this happens only if there is a problem parsing the string:
    bgColor_red = 255;
    bgColor_green= 255;
    bgColor_blue = 255;
Color bgColor = new Color(bgColor_red, bgColor_green, bgColor_blue);
setBackground(bgColor);and your HTML page parameters would look like this:
<PARAM name="bg_red" value="188">
<PARAM name="bg_green" value="188">
<PARAM name="bg_blue" value="255">
