JxBrowser supports HTML Input element with type=color and displays default Color chooser dialog where user can select required color. You can override default behavior by registering your own DialogHandler implementation with overridden onColorChooser() method where you can set the required color programmatically without displaying any UI dialogs. The following code demonstrates how to do this:

import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.CloseStatus;
import com.teamdev.jxbrowser.chromium.ColorChooserParams;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;
import com.teamdev.jxbrowser.chromium.swing.DefaultDialogHandler;

import javax.swing.*;
import java.awt.*;

 * This sample demonstrates how to override behaviour of standard
 * color chooser dialog for HTML5 input color element.
public class ColorChooserSample {
    public static void main(String[] args) {
        Browser browser = new Browser();
        BrowserView view = new BrowserView(browser);

        JFrame frame = new JFrame();
        frame.add(view, BorderLayout.CENTER);
        frame.setSize(700, 500);

        browser.setDialogHandler(new DefaultDialogHandler(view) {
            public CloseStatus onColorChooser(ColorChooserParams params) {
                return CloseStatus.OK;

        browser.loadHTML("<html><body><input type='color' value='#ff000'></body></html>");
