Average filter but the image is gray and not color RGB

Question

Hi,
i use this code for an average filter 3x3, the result is the image whit average but gray and not RGB color.... why??
thanks in advance
    public void Average()
        int values[]=null;
        int input2d[] = new int [image.getWidth()*image.getHeight()];
        int [][] output2d=new int [image.getWidth()][image.getHeight()];
        image.getRaster().getSamples(0, 0, image.getWidth(), image.getHeight(),0,input2d);
        for(int y=0; y < image.getHeight(); y++)
            for(int x=0; x < image.getWidth(); x++)
                int count = 0;
                int average=0;
          values = new int[5*5];
                for(int s = 0; s < 5; s++)
                    for(int r = 0; r < 5; r++)
                        try
                            values[count] = input2d[(y-2+r)*image.getWidth()+(x-2+s)];
                            count++;
                        catch(ArrayIndexOutOfBoundsException e){ }
                //trovo il valore medio dell'intorno 5x5
                for (int temp=0; temp<count; temp++)
                    average+=values[temp];
                int valpixel=average/count;
                output2d[x][y]=valpixel;
        image2 = new BufferedImage(image.getWidth(),image.getHeight(), BufferedImage.TYPE_INT_RGB);
        image2.getGraphics().drawImage(image,0,0,null);
        for(int y=0; y < image.getHeight(); y++)
            for(int x=0; x < image.getWidth(); x++)
                image2.getRaster().setSample(x, y, 0, output2d[x][y] );// componente R
                image2.getRaster().setSample(x, y, 1, output2d[x][y] );// componente G
                image2.getRaster().setSample(x, y, 2, output2d[x][y] );// componente B
    }
