It think this is what your looking for.  I have attached code below.  Chang
the code to use system colors.

     this.GripStyle = ToolStripGripStyle.Hidden;

     // Set renderer
     this._renderer = new FormHeaderTitleStripRenderer();

     // Look for headerText
     this.Renderer = this._renderer;
