setBackground(new color()); 在java中不了解给定的RGB值

Question

搜索谷歌半小时后,我放弃了!:)

在我设置的JFrame上,我有一个带有一些gui的程序,

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

[问题]它呈现出灰色,但不是正确的颜色!如果我在Photo Shop中检查gui的颜色,它会给我RGB值(126,125,123)

我真的很沮丧..有人有同样的问题吗？

PS.我尝试过HEX值,结果相同.

最好的问候,Juri

Answer 1

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

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

[The problem] It gives a greyish color, but not the right one! 
If I check the gui's color in Photo Shop, it gives me the RGB 
values (126, 125, 123)

你无法设置setBackground,例如JFrame,这只能ContentPane用于

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

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();
            }
        });
    }
