渐变背景色设置
法一：

graphics.setForegroundColor(ColorConstants.white);
			graphics.setBackgroundColor(
					DiagramColorRegistry.getInstance().getColor( rgb ));//200<<16|220<<8|230));
			graphics.fillGradient(getBounds(), true);

法二
先给SWT绘图，在设置图片背景色，然后将此图片作为背景图片进行设置

public Image getImage(Shell shell,int height,Device device){
		Rectangle bound = shell.getClientArea();
		Image image = new Image(device, Math.max(shell.getClientArea().width,1),height);
		GC gc = new GC (image);
		gc.setForeground (ColorUtil.getInstance().getColor(ColorUtil.Light_BLUE)/*shell.getDisplay().getSystemColor (SWT.COLOR_DARK_GREEN)*/);
		gc.setBackground (shell.getDisplay().getSystemColor (SWT.COLOR_WHITE));  
		gc.fillGradientRectangle (0, 0, bound.width, height, true);
		gc.dispose ();
		return image;
	}

例如给菜单栏设置背景图片：

Shell shell = getWindowConfigurer().getWindow().getShell();
Image img = getImage(shell, 25, shell.getDisplay());
setMenuBG(img);]

获取颜色：

Display.getDefault().getSystemColor(SWT.COLOR_DARK_GREEN);
ColorUtil.getInstance().getColor(ColorUtil.RED);

ColorUtil

public class ColorUtil {
	public static final String RED = "red";
	private static ColorUtil colorUtil = null;

	private ColorRegistry colorRegistry = null;

	private ColorUtil() {
		colorRegistry = new ColorRegistry();

		putColor(RED, new RGB(255, 0, 0));
	}

	public static ColorUtil getInstance() {
		if (null == colorUtil) {
			colorUtil = new ColorUtil();
		}
		return colorUtil;
	}

	public void putColor(String colorKey, RGB colorData) {

		colorRegistry.put(colorKey, colorData);
	}

	public Color getColor(String colorKey) {

		return colorRegistry.get(colorKey);
	}
}
