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.
To create your own color: Paint - Double click on any color at the bottom of the screen. - Choose "Define Custom Colors". - Select a color and/or use the arrows to achieve the desired color. are the numbers needed to create your new Java color.
Definition and Usage. The rgb() function define colors using the Red-green-blue (RGB) model. An RGB color value is specified with: rgb(red, green, blue). Each parameter defines the intensity of that color and can be an integer between 0 and 255 or a percentage value (from 0% to 100%).
Since 255 is the maximum value, dividing by 255 expresses a 0-1 representation. Each channel (Red, Green, and Blue are each channels) is 8 bits, so they are each limited to 256, in this case 255 since 0 is included.

[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)
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();
}
});
}
}
check with Adam's comment and even if not worked then without any working code I am just guessing that this scenario is getting raised due zero ordering or saying layout of the JFrame. Actually in java swing , setting the background color needs a little bit of more attention, check Swing Java Docs.
