(1)You can make you own Color Using Color Class Constructor with RGB Values. Search for Exact Color value you want
You can use new Color(100,149,237); or adjust these values as per your requirement

(2) You can use paint method to paint your image
maybe this can help

import java.awt.*;
import javax.swing.*;
class loginScreen extends JFrame
  public loginScreen()
    ImagePanel panel = new ImagePanel("test.gif");
    panel.add(new JButton("OK"));
  class ImagePanel extends JPanel
    Image img;
    public ImagePanel(String file)
      setPreferredSize(new Dimension(600, 400));
        img = javax.imageio.ImageIO.read(new java.net.URL(getClass().getResource(file), file));
      catch(Exception e){}//do nothing
    public void paintComponent(Graphics g)
      if(img != null) g.drawImage(img,0,0,getWidth(),getHeight(),this);
  public static void main(String[] args){new loginScreen().setVisible(true);}

You can use a JColorChooser to click the exact colour in the HSB tab or you can get the exact value in the RGB tab then specify the values of red,green and blue in your new colour as below;
Color lightblue = new Color(red,green,blue);

For the background you can try using look and feel coz it always works for me.
