setBackground(new color()); in java does not understand the given RGB value

Question

I have a program with some gui, on the JFrame I set,

 setBackground( new Color(107, 106, 104) );

The issue is that I get a greyish color, but not the right one. If I check it in PhotoShop, it gives me the RGB values (126, 125, 123)

Ps. I have tried with HEX value, the same result.

You can not set setBackground for JFrame, this is only possible for ContentPane, for example

JFrame#getContentPane.setBackground(new Color(107, 106, 104));

EDIT

from code

import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public class Check extends JFrame {

    private static final long serialVersionUID = 1L;

    public void makeUI() {
        JFrame f = new JFrame();
        f.getContentPane().setBackground(new Color(107, 106, 104));
        f.setDefaultCloseOperation(EXIT_ON_CLOSE);
        f.setSize(new Dimension(300, 200));
        f.setVisible(true);
    }

    public static void main(String[] args) {

        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new Check().makeUI();
            }
        });
    }
}
