Applying the Hatch brush element to a visual in your gauge gives that element a two-color patterned appearance.

Add a Radial Gauge to the Gauges collection.
In the left-hand pane of the Gauges collection editor, click Radial Gauge.
Expand the Dial property.
From the BrushElement drop-down list, select Hatch. This will create a new Hatch brush element.
Set the following properties:
BackColor — DimGray
ForeColor — Silver
