The ContrastAnalyzer can be applied to a TextBlock or Control to apply updates on its Foreground property.
When checking the original contrast ratio, the ContrastAnalyzer will attempt to grab the Foreground as a SolidColorBrush. If the original Foreground is not a SolidColorBrush it will default to Colors.Transparent, and always apply a raised contrast color.
If you are not using a TextBlock or Control, you can directly apply the ContrastAnalyzer to a SolidColorBrush.
