Problem Setting offscreen background

[D34N0]

Hi

I'm trying to create an applet with an image moving down the screen which i have been able to do, but when i try to set background of the offscreen image i get the following when compiling : symbol : method setBackground(java.awt.Color). Is there another way to set the offscreen background. Here is the code.
Many Thanks

PHP Code:

import java.awt.*;

public class KelvinIndexLogo extends java.applet.Applet implements Runnable {
    // Define Objects & Variables
    Image logo, workspace;
    Graphics offscreen;
    Thread runner;
    
    int logoY = 0;
    int logoStop;
    // Background RGB values
    int backRed   = 221;
    int backGreen = 221;
    int backBlue  = 221;
    boolean firstRun = true;

    
    public void init() {
        String imageName = getParameter("logo");
        setBackground(new Color(backRed, backGreen, backBlue));
        
        // Get the logo image if the logo parameter has been specified
        if(imageName != null) {    
            logo = getImage(getCodeBase(), imageName);
        }
    }
    
    public void start() {
        if(runner == null) {
            runner = new Thread(this);
            runner.start(); 
        }
    }
    
    public void stop() {
        if(runner != null) {
            runner = null;
        }
    }
    
    public void run() {
        // Move the Logo down from the top of the applet
        Thread thisThread = Thread.currentThread();
        while(runner == thisThread) {
            repaint();
            try{
                Thread.sleep(50);
            }catch(InterruptedException e){}
            
            // Would not get the correct image height in the init method
            // therefore created first run bolean to set the start & Stop points
            if(firstRun) {
                logoY    = 0 - logo.getHeight(this);
                logoStop = getSize().height - logo.getHeight(this); 
                firstRun = false;
            }
            
            logoY++;
            if(logoY == logoStop) {
                runner = null;
            }
            
        }
    }
    
    public void paint(Graphics screen) {
        // Create the workspace & offscreen objects on each iteration so
        // image is cleared every time and no black trail appears on text
        workspace = createImage(getSize().width, getSize().height);
        offscreen = workspace.getGraphics();
        
        offscreen.setBackground(this.getBackground());
        
        if(logo != null) {
            offscreen.drawImage(logo, 0, logoY, null);
        }
        
        // Draw workspace to screen & set background colour
        
        screen.drawImage(workspace, 0,0, this);
        
    }
    
    public void update(Graphics screen) {
        paint(screen);
    }
}

Problem Solved...

Create a filled rectangle the size of the image.
