The following example creates a FormattedText object and then applies several formatting styles to the text, including SetForegroundBrush.

		Protected Overrides Sub OnRender(ByVal drawingContext As DrawingContext)
			Dim testString As String = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor"

			' Create the initial formatted text string.
			Dim formattedText As New FormattedText(testString, CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight, New Typeface("Verdana"), 32, Brushes.Black)

			' Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
			formattedText.MaxTextWidth = 300
			formattedText.MaxTextHeight = 240

			' Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
			' The font size is calculated in terms of points -- not as device-independent pixels.
			formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5)

			' Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
			formattedText.SetFontWeight(FontWeights.Bold, 6, 11)

			' Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
			formattedText.SetForegroundBrush(New LinearGradientBrush(Colors.Orange, Colors.Teal, 90.0), 6, 11)

			' Use an Italic font style beginning at the 28th character and continuing for 28 characters.
			formattedText.SetFontStyle(FontStyles.Italic, 28, 28)

			' Draw the formatted text string to the DrawingContext of the control.
			drawingContext.DrawText(formattedText, New Point(10, 0))
		End Sub
