Changing the color of ToolStrip and MenuStrip

[C# Programming]

I want to change the default color of MenuStrip and ToolStrip controls in Windows Forms application (C#) which is blue, but when I change the background color, the controls become flat. For instance, when I change the color of the ToolStrip control, I lose the 3D look and the control becomes flat. Is there a way to maintain the 3D look of these controls when I change their background colors? Thanks.
