You can configure the selected tab to display a gradient background using CTabFolder's setSelectionBackground() method.

import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CTabFolder;
import org.eclipse.swt.custom.CTabItem;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class CTabFolderGradientBackground {
  public static void main(String[] args) {
    Display display = new Display();
    Shell shell = new Shell(display);
    shell.setText("Show CTabFolder");

    shell.setLayout(new GridLayout(1, true));

    CTabFolder tabFolder = new CTabFolder(shell, SWT.TOP);
    tabFolder.setBorderVisible(true);
    tabFolder.setLayoutData(new GridData(GridData.FILL_BOTH));

    // Set up a gradient background for the selected tab
    tabFolder.setSelectionBackground(new Color[] {
        display.getSystemColor(SWT.COLOR_WIDGET_DARK_SHADOW),
        display.getSystemColor(SWT.COLOR_WIDGET_NORMAL_SHADOW),
        display.getSystemColor(SWT.COLOR_WIDGET_LIGHT_SHADOW) }, new int[] { 50, 100 });

    new CTabItem(tabFolder, SWT.NONE, 0).setText("Tab index 1 ");

    shell.open();
    while (!shell.isDisposed()) {
      if (!display.readAndDispatch()) {
        display.sleep();
      }
    }
    display.dispose();
  }
}
